aobench crash #26

Closed ib00 closed 8 months ago

ib00 commented 8 months ago

Cool project!

I am trying to run aobench sample and I get a segmentation fault on linux. (two Vulkan devices: AMD Radeon Graphics (RADV RENOIR), and NVIDIA GeForce RTX 3050 Laptop GPU)

There are several messages before the crash: 'LEA used on a pointer to a non-array type!'

Hi, this isn't sufficient information to reproduce/diagnose. The message you got is just an unrelated warning, you can safely ignore it. You can compile in Debug mode and run it through a debugger to get a better idea of what's wrong. Also enable verbose logging through --log-level.

Thanks for your reply.

I ran it in debug mode The crash happens in nvidia driver:

Thread 1 "aobench_host" received signal SIGSEGV, Segmentation fault. 0x00007fffd7385162 in ?? () from /usr/lib/libnvidia-glvkspirv.so.535.113.01

Stack trace (omitting stuff from nvidia drivers):

If I run the aobench on AMD (integrated) card, it crashes in:

I can report that this crash went away with one of the commits (fd8acfd, 14e6287). Thanks!

Cool! I still need to port aobench to the vcc path though ^^'
