`PhysicalDeviceSelector::select` crashes #289

Closed n0F4x closed 5 months ago

n0F4x commented 5 months ago

I get a SIGTRAP right here in the second iteration (for the second device). The SIGTRAP happens inside the vector's push_back when folding its call stack. But I'd guess the error is rather with the PhysicalDevice's (move/copy) constructor.

Environment: Clang (LLVM) 17.0.6

I couldn't test my project with other compilers as they all have some missing features. The first commit that doesn't work is here.

Can you post your code? Hard to know what’s wrong without seeing how your code works.

This is where I call PhysicalDevice::select in my code

I am also suspicious of PhysicalDevice::extended_features_chain when it gets moved/copied. The pNext pointers should still point to the right next feature.

I had a very weird setup where I was using an outdated VkBootstrap header. Dropping that header and only using the new one runs fine.

So the problem was on my end.
