Bug Description

Symptoms: attaching gdb to any program that uses pthreads will result in fatal errors like "Cannot find user-level thread for LWP 192701: generic error"

The upstream bug is https://sourceware.org/bugzilla/show_bug.cgi?id=27744

It looks like the fix has already been adopted in https://launchpad.net/ubuntu/+source/glibc/2.33-0ubuntu7 , but it needs to be backported to 21.04/hirsute
