I forward it here for comments.
Basing on the behavior of both GCC and Clang, `__cxa_thread_atexit` is used to
register the
destructor of thread_local objects directly, suggesting the first parameter
should have `__thiscall`
convention.
libstdc++ used the default `__cdecl` convention and caused crashes on
1686-w64-mingw32 (see
PR83562). But to my surprise, libcxxabi uses `__cdecl` too [1], but I haven't
heard any of relevant
reports so far.
Original patch is attached in case you can't find it in gcc-patches.
FWIW, this patch looks good and correct to me, from a mingw perspective.
