Compilers usually warns or errors on such allocations. This would require special compiler parameter or attribute to silence it. Unfortunately, it is compiler specific, e.g. with gcc one could use "__attribute__ ((nonstring))" or with C23 just "[[nonstring]]" or gcc parameter "-Wno-error=unterminated-string-initialization". With other compilers it's different. So do not over-complicate things and allocate it just one more byte longer with the dummy NULL which should silence most of the compilers. It's static allocation, just one byte, the overhead should be negligible. Signed-off-by: Jaroslav Škarvada <jskarvad@redhat.com>

Fedora recently switched to the gcc-15 with C23 as the default standard and tighten the checks, so without the patch it fails to compile with the default compiler settings, downstream Fedora bug: https://bugzilla.redhat.com/show_bug.cgi?id=2340611 |
