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.
