reducing the contention in dl_iterate_phdr (reloaded)

[Vincenzo Innocente]

I found this old thread about lack of concurrency in  dl_iterate_phdr that affects gcc unwinding.
https://sourceware.org/pipermail/libc-help/2020-May/005275.html

I discover this issue while experimenting with C++23 std::stacktrace in a multithread application.

Has been made any progress on the subject since May 2020?


   cheers,
