--- Comment #30 from Jonathan Wakely <redi at gcc dot gnu.org> --- Created attachment 45940 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45940&action=edit Patch to fix resource_adaptor failures due to max_align_t bugs Could you please try this patch on Soalris and HP-UX? Commit log: Remove the hardcoded whitelist of allocators expected to return memory aligned to alignof(max_align_t), because that doesn't work when the platform's malloc() and GCC's max_align_t do not agree what the largest fundamental alignment is. Instead use a hardcoded list of fundamental types that will definitely be supported by the platform malloc, and use a copy of the allocator rebound to the first type that matches the requested alignment. This means allocations for alignof(__float128) might use additional memory to store the token, because we can't assume the platform malloc will return memory aligned to alignof(__float128). Ideally we'd be able to add __float128 to the list of fundamental types when we know it works for a given target.
