Summary: Test strncmp() function : usage variations - binary
safe(binary values)
Status: Open
Type: Bug
Package: Testing related
Operating System: Ubuntu 16.04 LTS on aarch64
PHP Version: 7.1.1

New Comment:
This test[1] confuses binary strings and binary numbers, and
should better be rewritten or dropped, anyway.
Furthermore, and this is might be the reason for the reported test
failure, the test assumes that strncmp() would return exactly 1,
if the first string is greater than the second, but strncmp() only
guarantees that a positive integer is returned in this case.
