GCC build is also broken (results in SIGSEGV during build), so this is likely related to FreeBSD using libc++. 1881898 1 2khramtsov 2022-07-09 14:07:35 -0700 This is caused by std::pair ABI incompatibility in FreeBSD https://reviews.freebsd.org/D35327 2091010 2 vishwin 2025-01-31 09:29:47 -0800 This should be obviated by bug 278596, but for future reference, std::pair copy constructors are never trivial in FreeBSD due to continued use of LLVM libc++ ABI version 1.
