<div>
<pre>This suite of tests crashes intermittently on BSW
repeatedly running the single test
dEQP-VK.api.object_management.multithreaded_per_thread_device.shader_module
should generate a segfault about 25% of the time.
The stacktrace leaves mesa for libgcrypt at src/util/mesa-sha1.c:190
gcry_control(GCRYCTL_INITIALIZATION_FINISHED, 0);
Mesa initializes libgcrypt on first use, based on a static int. This is not
sufficient to protect the initialization routine from simultaneous execution.
Based on
<a href="https://gnupg.org/documentation/manuals/gcrypt/Multi_002dThreading.html#Multi_002dThreading">https://gnupg.org/documentation/manuals/gcrypt/Multi_002dThreading.html#Multi_002dThreading</a>
there should be a real mutex here.</pre>
