Hi,
I am analyzing a crash dump of my window application which runs for 3 days and then crashes with "INVALID_POINTER_READ" error. below are the register details:
CONTEXT: (.ecxr)
rax=0000000000000000 rbx=0000026591824f40 rcx=3465623838353134
rdx=0000000000000000 rsi=0000000000000001 rdi=0000000000000000

cs=0033 ss=002b ds=002b es=002b fs=0053 gs=002b efl=00010206
FieryJDF!wxCondition::Signal+0x4:
00007ff6233470c4 488b09 mov rcx,qword ptr [rcx] ds:3465623838353134=????????????????
Resetting default scope
The call stack suggest, there is a signal call done with wxCondition::Signal() but the wxCondition* pointer contain bad or invalid address ":34656238`38353134" which rcx register is currently holding.
can someone suggest where to check which thread/process user or kernel causes this corruption of wxcondition* pointer variable.??

Product: WinNt, suite: SingleUserTS
10.0.14393.2430 (rs1_release_inmarket_aim.180806-1810)Regards

Other than that, I would need to see way more of your app.
If I were to take a wild guess.
Maybe thread exhaustion.
Do you use anything on tasks like .Wait() or .Result()?
