--- Comment #29 from Alejandro Colomar <alx at kernel dot org> --- Hi Kees, (In reply to GCC Commits from comment #28) > The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: > > https://gcc.gnu.org/g:622968990beee7499e951590258363545b4a3b57 I guess I should have reviewed the commit message when I was in time. Anyway, here are a few comments for next time. :-) > > commit r15-7900-g622968990beee7499e951590258363545b4a3b57 > Author: Jakub Jelinek <ja...@redhat.com> > Date: Fri Mar 7 23:59:34 2025 +0100 > > c: do not warn about truncating NUL char when initializing nonstring > arrays [PR117178] > > When initializing a nonstring char array when compiled with > -Wunterminated-string-initialization the warning trips even when > truncating the trailing NUL character from the string constant.

If I'm understanding it correctly, I think the first sentence refers to the behavior before this patch? If so, using past might have been clearer. > gcc/c/ > * c-typeck.cc (digest_init): Add DECL argument.

You meant NUL, which is the ASCII name for the null byte. Cheers, Alex
