Description unhappy-ending 2022-03-17 02:10:03 UTC 
When compiling media-libs/harfbuzz with Clang plus any optimization level greater than 0, the test phase will fail. When set to -O0, test phase passes. No such problems with GCC.

Thanks!

Could you please report the issue upstream & link it here?

Also, include /etc/portage/package.tmp/portage/media-libs/harfbuzz-4.0.1/work/harfbuzz-4.0.1-abi_x86_64.amd64/meson-logs/testlog.txt.
Comment 4 unhappy-ending 2022-03-17 03:18:16 UTC 
While looking for the test.log in abi_x86_64 I noticed it didn't exist and realized that's because the test phase failed before it got to the 64 bit tests. Those pass fine, just tested, adding a new build log.

Upstream: https://github.com/harfbuzz/harfbuzz/issues/3483
Comment 7 Matt Turner gentoo-dev 2022-03-17 04:40:02 UTC 
For clarity: I think the report is that tests fail when harfbuzz is compiled for 32-bit x86.
Comment 8 unhappy-ending 2022-06-21 08:05:36 UTC 
FWIW this is a Clang + LLVM toolchain built system. 

I've been doing more testing on this. It seems to do with dev-libs/glib, will report more when I can whittle it down to what's causing the problem.
