CommandPool destructor crash on exit

[rolandhill]

Hi Robert,

I've just starting getting a crash in the CommandPool destructor on exit using VSG master from this morning. The terminal output is:
malloc_consolidate(): unaligned fastbin chunk detected

It doesn't crash all the time, but has happened maybe 6 times today.

I do add and remove branches during execution, so descriptorSets are being recycled. For testing purposes, I'm just using master rather than #961, although I notice that automatic building has just stopped working for that PR, so maybe your working in the area now.

I'm on Kubuntu 22.04 and Nvidia 3070Ti.

Some debugging screen shots follow:

Regards,
Roland

I haven't touched the CommandPool functionality recently, neither the Animation or Instrumentation work touch upon it, so I wouldn't have thought recent changes would have caused a regression.

Do any of the VSG examples have show this problem?

Do you see any errors reported when you enable Vulkan debug layer?

Is you application multi-threaded? Is so try running single threaded if possible to see if that has an effect.

I think it only happens if I close my application while an ImGui window is open. It might be a problem at my end. Leave it with me. Cheers, Roland

Hi Robert,

This one's on me. I was calling an overridden method (cleanup functions) in a derived class from the destructor of the base class. It just happened to randomly crash in CommandPool.

Cheers,
Roland
