pthread_create.c:713 : if (pd->stopped_start)

Probably could be caused by a bug in Glibc.

Not reproducible on Ubuntu 20.04.4 LTS (GNU/Linux 4.15.0-74-generic x86_64) Source: master (c1a6378297) Test runs: >7000 gcc version: gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0 glibc version: ldd (Ubuntu GLIBC 2.31-0ubuntu9.9) 2.31

But glibc version (2.31) is older than originally reported (2.33).
