libstdc++ segfault at end of execution

Hi Lance,

I'm having segfaulting issues with c++ on aarch64 using uclibc-ng. Anyone else using aarch64 with uclibc-ng?
I submitted a bug to gcc so am linking that here for this description.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106581
Some years ago, I switched from uClibc to musl on aarch64, because uClibc did not fully implement thread-local storage, at least not in combination with multi-threaded execution, on this architecture.
The C++ library uses TLS for example to store exception related information, which, in my case resulted in a segmentation fault whenever the first exception handler was invoked, because the TLS area was inaccessible from the current thread.
My notes show that tests in 2021 still showed this problem.
Kind regards,
Andreas
