Debug crash from stack trace that only shows Qt code

Joel Bodenmann

Hello folks,

Every so often when I close my Qt program it crashes. I immediately fired up the debugger to fix the problem ASAP. However, I'm totally lost on this one. The stack trace does not show any of my custom code: screenshot
I'm really not sure where to begin (and how) for tracking this issue down in order to fix it.

The other thing I noticed is the following output on the console which I highly assume is related to the problem:

HEAP[uGFXStudio.exe]:
HEAP: Free Heap block 15F094D0 modified at 15F09504 after it was freed

Any help would be appreciated.

Hi,

What kind of model are you using ?

Joel Bodenmann

@SGaist I subclassed the QAbstractItemModel.

Then, are you modifying some data after it's being freed ?

1 : Could you post minimum codes to generate the errors?

2 : If this question seem stupid please ignore it, did you try to static link to the dll of Qt?
