Building posix/bug-regex22.c fails with GCC mainline because of -Wformat-overflow= warnings for NULL arguments to %s formats. This is *not* testing how glibc handles such format arguments; in the context of the messages in question it makes no sense to pass NULL to such a %s format (the code passes s, inside "if (s == NULL)"). So this patch changes the code not to pass such a format argument at all (which means the string passed is constant, so no need to use printf at all - however, there are two separate tests here with different length arguments passed to re_compile_pattern, so it *does* make sense to make the strings used different so that in the event of failure it's clear which one of the tests failed). Tested with build-many-glibcs.py with GCC mainline for aarch64-linux-gnu. * posix/bug-regex22.c (main): Use puts with distinct error messages for unexpected success of re_compile_pattern, not printf with NULL argument to %s.
