Hey all,
I just started working on my graphics layer today and have ran into a really weird bug that I think is a problem with the Vulkan driver?
To explain, I'm running CachyOS with the 7.2 kernel, and the latest NVIDIA driver (proprietary). I was working on getting aligned memory allocations working (a lot up-front but it's worth it!) and I juuust managed to get all of that patched so it would function. Except, for some reason I'm getting a segfault in a `realloc()` call that I'm not making, and it's coming from several layers of indirection inside `libvulkan` which I can't debug properly. This issue seems to be particular to my own implementation, as every other application using Vulkan is fine, but can anyone else test my code and let me know if I'm going insane? I'm probably going to rewrite the allocator anyways because it's still super messy.
Thanks!
Ah, it's a implementation detail. I was storing the VkAllocationCallbacks structure as a static object in the source file, which NVidia doesn't like apparently and that was causing the driver to crash. Very weird bug and I suppose it's something I missed with regards to how the spec is worded!
