https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113752 --- Comment #7 from Jakub Jelinek --- Anyway, I think the testcase is very similar to char a[256], *c, *g; int foo (void) { if (__builtin_strlen (c) + __builtin_strlen (g) + 5 > 256) return 0; __builtin_sprintf (a, "abcd%s%s", c, g);

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113752 --- Comment #6 from H.J. Lu --- I can reproduce it with r14-8930-g1e94648ab7b370

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113752 --- Comment #5 from Jakub Jelinek --- That said, the math at least in the reduced testcase is weird. %d output is at most 11 bytes - strlen ("-2147483648"), + 9 other chars, so that is 42, not 32. But even using + 42 in there instead of 32
