After fixing (or working around?) #1142193 with the patch that I
attached there, when I try to build vkd3d in an armhf chroot on the
arm64 porterbox amdahl, most of the test suite segfaults.
I was able to get this backtrace, which seems like the issue might be in
generated code (?) in Mesa, rather than vkd3d, if it helps:
smcv@amdahl ~/vkd3d % p=$(basename "$(pwd)"); d=; a=armhf;
s="smcv${p:+"-$p"}${d:+"-$d"}${a:+"-$a"}"; schroot -c "$s" -r -- libtool --mode=execute
