Shouldn't this bug be resolved as fixed, then?

It seems different. With Debian bug 884075, the "|^1?$" part is important (it yields the incorrect output, even though this part isn't matched), and there is nothing like that in glibc bug 10844:

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

Note that for the first command, nothing is colored in "11111111111", i.e. the line is output as appeared to be matched, but no matches are shown by colors. As a comparison, with ten 1s instead of eleven, the line is output and the ten 1s are colored.
