Could you please tell us what type of app are you developing? win32 application or c# application?

Code 0xC0000374 is STATUS_HEAP_CORRUPTION (A heap has been corrupted.) I suggest you could try to fix it by running it in debug mode under a debugger. Refer to the thread: https://stackoverflow.com/a/15663130/11872808

What do you mean "Mix Platform application"?

The big issue with this type of error is that it is almost always a programmer error.

The code in question has corrupted the heap control block and when the code then tries to free the memory, the Windows heap manager reports the error.

An obvious and deliberate C++ example that shows this happening is:

#include <memory> int wmain() { char *p = new char[10]; char *o = p - 8; o[0] = 'a'; o[1] = 'b'; delete[] p; return 0; }

This code allocates a block of memory, deliberately moves the pointer back by 8 bytes and then writes to that memory. When delete[] p executes, the following is reported in the debugger:

Critical error detected c0000374

A breakpoint instruction (__debugbreak() statement or a similar call) was executed in cctest.exe. In Event Viewer, it is reported as:

In other words, a bad application can have an error reported seemingly in the Windows libraries themselves. But this is an error in the user code.

Answer 1

The error code 0xc0000374 indicates a heap corruption issue, which can be caused by various factors, including:

Incorrect memory access or management: This can occur due to bugs in the application code, libraries, or dependencies.
Outdated or corrupted system files: This can happen if the operating system or .NET Framework is not up-to-date with the latest patches and updates.
Malware or viruses: Malicious software can cause heap corruption and crashes.
Hardware issues: Faulty RAM or other hardware problems can lead to heap corruption.

To troubleshoot and potentially resolve the issue, consider the following steps:

Update your system and drivers: Ensure that your operating system, .NET Framework, and drivers are up-to-date with the latest patches and updates.
Run system file checks: Use tools like sfc /scannow and DISM to repair corrupted system files.
Reinstall problematic apps: If the issue is related to a specific application, try reinstalling it.
Perform a malware scan: Use antivirus software to scan your system for malware and viruses.
Use a memory diagnostic tool: Tools like MemTest86+ can help identify hardware issues related to RAM.

Additionally, consider the following:

Review recent changes: If the issue started after a specific date, review any changes made to your application or environment around that time.
Analyze crash dumps: If possible, analyze crash dumps generated during these crashes to identify patterns or specific code paths leading to the crash.
Check Event Viewer: Look for additional information in the Event Viewer, such as error messages or warnings related to the crash.

Answer 3

The error code 0xc0000374 typically indicates a heap corruption issue, and it's a bit generic.

Here are a few steps you can take to troubleshoot and potentially resolve the issue:

Check for Windows and .NET Updates: Ensure that your Windows operating system and .NET Framework are up-to-date with the latest patches and updates. Microsoft frequently releases updates to address known issues and improve stability.
Review Recent Changes: Since the issue started after a specific date, review any changes made to your application or the environment around that time. This includes updates to dependencies, libraries, or any modifications to the code.
Analyze Crash Dumps: If possible, analyze crash dumps generated during these crashes. Tools like WinDbg can help you analyze memory dumps and identify the root cause of crashes. Look for any patterns or specific code paths leading to the crash.
Check Event Viewer: The information you provided is from the Event Viewer. Check for additional information in the Application or System logs. There might be more details or specific error messages that can help diagnose the issue.
Memory Issues: Heap corruption often indicates a problem with memory. Check for any memory-related issues in your application. Ensure proper memory management, avoid buffer overflows, and consider using memory analysis tools.
Update .NET Framework Version: If possible, consider updating your project to a more recent version of .NET Framework. This might include migrating to .NET Core or .NET 5/6, as older versions may have known issues that have been addressed in newer releases.

I hope that helps you.
