--- Comment #1 from Danylo <danylo.piliaiev at gmail.com> ---
The tests are crashing due to allocation failure after running for some time
which is caused by enormous size of the resulting native code of the shaders.

Initially it was bisected to:

anv/pipeline: Move lower_explicit_io much later

Now that nir_opt_copy_prop_vars can properly handle array derefs on
vectors, it's safe to move UBO and SSBO lowering to late in the
pipeline. This should allow NIR to actually start optimizing SSBO
access.

However this commit just triggered the underlying issue - force loop unrolling
without any check for resulting unrolled size.

I've sent a merge request to fix this:
