Hello, I am a CS student, and I have an assignment in OOP(*disclaimer, I already submitted the project, so I'm not looking for guidance).
The teacher gave us an image with the expected result, and the Main.cpp file, and we had to "reverse engineer" the functions he provided, and write them ourselves to match the output he has given us.
The project itself includes Main.cpp, Polynomial.cpp, Rational.cpp, Polynomial.h and Rational.h files.
When I run the project on my laptop(Windows 11 if that matters, and VS 2022 community edition), the program "crashes" just before the end of the file, but when I run the same project, on a different computer(I've tried several computers, some were running Windows 10, and some Windows 11, and VS 2022 or VS 2019 community editions), and everything runs just fine.
I even tried reinstalling VS completely, and restore all it's settings to default, and I also tried making an entire new project on a different directory, and nothing worked. I tried disabling the Anti-virus, tried running the program via CMD(and PowerShell), and I checked the project settings to see if anything is out of the ordinary, but nothing "popped up".
When I run the program with the debugger, it runs just fine, no exceptions or errors whatsoever.
I can't find any solutions online regarding this issue, so I was hoping someone here might have a clue on why it's happening.
I provided the image with the result I'm getting when running the debugger, and one when I run it without the debugger.
Thank you in advance.

What there leads you to believe its crashing?

Can you describe what the crash looks like and if there are any error messages？ Where in the screenshot do you think it crashed？

On the first picture, the program doesn't print the "exited the code with..." Also you can see that the print itself is messed up for some reason(like why would it print test2 on the right side?).

I believe it crashes right before it reaches the end of the program. However there are no error messages whatsoever. When running with the debugger, it reaches the end of the program just fine.
I have a print function in Rational.cpp file which prints 2 Polynomials. If I comment that function(and all the lines in the Main.cpp file which calls the print function in Rational) the entire code prints out just fine(except the lines where I print Rationals). Test #7 and test #8 are both printed in Rational for example. This is my main suspicion. P.s. Running the debugger to check where the print is getting messed up doesn't work as it prints out just fine, so it is impossible to find which line or what function is causing the problem.
(Ignore the code itself)
void Polynomial::print() const
{
cout << "polynomial = ";
int j = degree;
int i = 0;
while (j > 0)
{
if (coefficient[j] != 0)
{
break;
}
else
{
j--;
}
}
if (j == 0)
{
cout << coefficient[0];
}
else
{
for (i = 0; i < j; i++)
{
if (i == 0)
{
cout << coefficient[i] << "+";
}
else
{
cout << coefficient[i] << "X^" << i << "+";
}
}
cout << coefficient[i] << "X^" << i;
}
cout << "\n";
}
void Rational::print() const
{
nom.print();
cout << "--------------------------\n";
denom.print();
}
Without seeing the entire code it's hard to guess where problems are. Have you enabled all run time check options in your debug build and run the static code analysis on your projects to see if they show any possible issues?

Yes I have enabled all run-time checks. I also tried running analyze on the solution and the project, and the only errors appearing are about casting, which I fixed and uninitialized variables(only 2 times in the entire project where there was a line of int i; which I changed to int i = 0;) and it's still occurring. If needed, I can upload the entire project or something like that. I feel really lost because I've tried every single suggestion I could find, and none solved the issue.
If you post a zip of the solution somewhere anyone can get it (such as a OneDrive share) and a link to it here, I'm sure someone will find time to have a look at it.
https://1drv.ms/u/s!AnLvXxXXBhHm80RszDLb8P_oQST_?e=x2XckC That's the ZIP containing the cpp and header files
Hi, can you provide the contents of main.cpp? It will help us reproduce your problem.
@Minxin Yu Yes, sorry, I forgot they said not to send the main.cpp within the zip file. https://1drv.ms/u/s!AnLvXxXXBhHm80DmKNNyHHKTi6Ts?e=usgptV
Hi，@Ido Berkovits
I reproduce your problem successfully. Apparently this is a bug with Visual Studio and it happens randomly.
The first time I ran the program without debugging:
And second time I removed a space in snippet and rebuild the program again.
Before: cout << "test10 :maxDegree = " << Polynomial::getMaxDegree() << endl;
After: cout << "test10 :maxDegree = " << Polynomial::getMaxDegree()<< endl;
You could report the problem to Developer Commnunityand post link here.
Best regards,
Minxin Yu

@Minxin Yu
First of all, thank you for the effort you're putting to help diagnose the problem, it's much appreciated and not taken for granted at all!
Second of all, I've tried doing what you suggested and it didn't work for me, the issue still persists, However, when I commented all the lines where GetMaxDegree function was called(lines 17, 37 and 67) the program runs just fine.

I got a more impressive screenshot:
Yeah, had that happening as well. The output, even while buggy, is inconsistent.
FWIW, using the latest VS 17.6.0 Preview 3, I've been unable to reproduce your problem. You might like to try with that version to see if you can still reproduce it or not. If you can still reproduce it, ensure your bug report has a complete solution (not just the source files you've shared) so that MS is testing the same thing you have.
Also note that I think your code as presented doesn't need the currDegree member variable of the Polynomial class as its only used in the setCoeff method, and the getCoeff method has logic conditions that can't arise.
