Comment # 18 on bug 97305 from Matias N. Goldberg

You're awesome!

I can confirm it works on both the sample repro I provided and my actual real
case.

Small note: We discovered there was a potential for a crash because at certain
points we assume SIMD alignment; so we're now enforcing 16-byte alignment as
minimum in our code. I'm doing this remark because Mesa is the only (or among
the very few) implementations that return alignments <16; which can reveal
hidden bugs in program code that runs fine everywhere else. If you ever see a
bug report of these sorts (e.g. crashing in movaps, movntdqa), this is
something to keep in mind.

I appreciate the 4 byte alignment as 256 reported by others is excessively
wasteful. Thanks.
