--- Comment #27 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Ben Elliston from comment #26) > This test now passes on powerpc*-linux-gnu. I wonder how ... the "fix" got reverted, and we still use an allocator of char to create the storage for the COW string's _Rep, which has stricter alignment requirements than char. The array_allocator was eventually removed in 2019, because it was broken. But the alignment problem still seems to be present in the COW std::string.
