Bug 10844 actually seems to be a different bug.
I've reported bug 29560 upstream concerning 1111111111111.

So there are 3 upstream bugs concerning bad results with backreferences
(but the regexp's are rather different is each case):

  https://sourceware.org/bugzilla/show_bug.cgi?id=10844
    (ab*){1,9}\1

  https://sourceware.org/bugzilla/show_bug.cgi?id=17356
    (.{0,1})(.{0,1})(.{0,1})\3\2\1

  https://sourceware.org/bugzilla/show_bug.cgi?id=29560
    ^(11+)\1+$|^1?$
