[TSAN] Crash while creating a vulkan device #165104
Description
The original issue for this can be found in: google/sanitizers#1678
However since the repo mentions that issues should be opened here, this opens the same issue here.
There is a crash on a memory read inside of libnvidia-glcore.so when calling vkCreateDevice. This occurs even when attempting to ignore calls from the lib via a suppression file.

The original issue does contain the following explanation for the issue:
The issue arises because malloc/calloc/free calls in the driver are correctly intercepted by TSAN but pthread_* calls are not. The NVIDIA driver is built with older glibc headers, which we need in order to maintain support for older linux distributions. Because of this, the driver picks up old versions of libpthread that TSAN does not interpose. Conversely malloc/calloc/free only have one version, so interposition is unhindered. When a pthread created without TSAN's pthread_create interceptor enters TSAN's calloc interceptor, that ThreadState struct mentioned above is uninitialized, resulting in the segfault.
This issue makes the use of tsan impossible in applications like video games. Is there any workaround for this or a way to handle this in tsan?
