test-case
Knowing the warning has a significant false-positive rate, but still, it may be
an interesting test-case. It's reduced from xen package:
$ gcc bunzip.i -Werror=maybe-uninitialized -O1
bunzip2.c: In function ‘get_next_block’:
bunzip2.c:261:27: error: ‘length’ may be used uninitialized
[-Werror=maybe-uninitialized]
bunzip2.c:224:17: note: ‘length’ declared here
cc1: some warnings being treated as errors
