--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
GCC 11 and 12 print the following for the test case in comment #0. I believe
the problem has been resolved (the %G format is gone now from 12).
pr83429.c: In function ‘void test(S*)’:
pr83429.c:12:42: warning: ‘%s’ directive output may be truncated writing up to
9 bytes into a region of size between 5 and 14 [-Wformat-truncation=]
12 | snprintf(s->out, sizeof(s->out), "%s.%s", s->str1, s->str2); //
line 12
| ^~
pr83429.c:12:13: note: ‘snprintf’ output between 2 and 20 bytes into a
destination of size 15
12 | snprintf(s->out, sizeof(s->out), "%s.%s", s->str1, s->str2); //
line 12
| ~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
