What is the status of this bug? The comment says that it is fixed, and I co=
uld
check on an Ubuntu 22.04.1 LTS machine with libc6 2.35-0ubuntu3.1 that regb=
ug.c
and rebug2.c no longer fail, but the result is still incorrect with the grep
example from Debian bug 884075:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=3D884075

vinc17@gcc92:~$ echo 11111111111 | grep -E '^(11+)\1+$|^1?$' ; echo $?
11111111111
