What about attachment 10674 ("This test case silently returns the wrong answer"), with the pattern "^(11+)\\1+$|^1?$" and the string "1111111111111"?
Should it be regarded as part of Bug#17356 or another bug? This case seems quite different from Bug#10844 and Bug#17356. Unless the intent is to group all the bugs about regexp involving backreferences giving a wrong answer[*] (in which case Bug#10844 and Bug#17356 should be regarded as duplicates to each other), I think that this should be a new bug. [*] as opposed to a crash like in this bug 11053. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to grep in Ubuntu. https://bugs.launchpad.net/bugs/1940996 Title: test failure - test-regex Status in grep: Fix Released Status in grep package in Ubuntu: New Bug description: 'test-regex' fails when building grep against glibc 2.34. Per commentary from grep upstream at https://debbugs.gnu.org/cgi/bugreport.cgi?bug=50069, the test failure can be attributed to skew between the glibc built-in regex and the one that is found in the grep source code.
