regex-test fails in 2.22.4

[Matthew Burgess <matthew linuxfromscratch org>]

Hi,

Running 'make check' on glib-2.22.4 shows that 'regex-test' fails.  I 
ran './regex-test --noisy | grep failed' that shows the following:

partial matching (string: "aa", pattern: "a+b")      failed  (got 1, 
expected: 0)
466 tests passed, 1 failed

Is there anything I can do to debug why this is failing for me, or is 
this a known issue?

Thanks,

Matt.
