Crash reproducer run script
Attached: run script.
Due to attachement size limit, the pre-processed source is available at:
https://drive.google.com/file/d/1HRPD-gvtsuXKKTkoI5ozfGcvBvj9QnYy/view?usp=sharing
The compiler was being run on a Skylake X CPU, on source making use of AVX512
intrinsics (potentially including some of the newer instruction sets).
