At the bottom of anv_GetSemaphoreFdKHR:
/* From the Vulkan 1.0.53 spec:
* "Export operations have the same transference as the specified handle
* type’s import operations. [...] If the semaphore was using a
* temporarily imported payload, the semaphore’s prior permanent payload
* will be restored.
if (impl == &semaphore->temporary)
If this happens, the underlying semaphore resource is released but the semaphore type is not updated to NONE.
So, on Destroy, the semaphore resource will be released again.
I think instead it should be:
This should be fixed by the following commit on master:

anv: Set fence/semaphore types to NONE in impl_cleanup
There were some places that were calling anv_semaphore_impl_cleanup and
neither deleting the semaphore nor setting the type back to NONE. Just
set it to NONE in impl_cleanup to avoid these issues.
