--- Comment #1 from Konstantin Kompan <atomnik07 at gmail dot com> ---
Can confirm for gcc 15.1.0, MSYS2.

Exiting a thread with static thread_local std::string variable seems to be
randomly causing program termination in about half of cases. Backtrace shows
that it's caused by destructing the string, which has __p = 0xfeeefeeefeeefeee,
which means that this memory has been freed already.
