[Comment 1 Matt Turner 2017-03-24 19:04:07 UTC]

This happens for me too, with libcxx-3.9 and 4.0.

Marking as a blocker of llvm-4.0 keywording.

Looks like we're not the only ones having trouble with this. I'll just skip libcxx for ppc* for now.

    profiles/arch/powerpc: Mask clang-runtime[libcxx], #595744

[Comment 3 Arfrever Frehtes Taifersar Arahesis 2021-02-03 22:21:42 UTC]

https://bugs.llvm.org/show_bug.cgi?id=39696

Original problem is supposedly in GCC, but workaround in libcxx was applied:

https://github.com/llvm/llvm-project/commit/3bf63cf3b366d3a57cf5cbad4112a6abf6c0c3b1
https://github.com/llvm/llvm-project/commit/0583d9ea8d5edc60d84971ced29db042b59302ba
https://github.com/llvm/llvm-project/commit/d9a42ec98adcb1ebc0c3837715df4e5a50c7ccc0

Last fix is included in libcxx >=11.0.0.
