libgcc12: ASAN_OPTIONS=detect_leaks=1 causes apparent hang

Port: libgcc12

Description

When running a binary I've compiled with -fsanitize-address with the ASAN_OPTIONS variable set to detect_leaks=1, the process appears to never terminate.

I note that when also adding leak_check_at_exit=0 this doesn't occur, but it also doesn't catch any leaks that exist at exit time. Further, calling __lsan_do_leak_check() manually (with either leak_check_at_exit=0 or not) causes the hanging behaviour.

Attached is a reproducible script, and the output.
