This looks like PR #29922, but I'm hitting it on the trunk while compiling
tcp-wrappers-7.6. It didn't fail on my last system rebuild a week or two ago.
Using built-in specs.
Target: x86_64-pc-linux-gnu

------- Comment #3 from rguenth at gcc dot gnu dot org 2008-10-31 12:18 -------
Reduced testcase:
void percent_x(int ch, char *p, char* ok_chars)
{
char *cp = ch == 'a' ? p : "";
for (;*(cp += __builtin_strspn (cp, ok_chars));)
;
}
__builtin_strspn is partially redundant for cp == "" (it's zero). The
zero is of wrong type becaue fold_builtin_strspn returns integer_zero_node
instead of size_zero_node.
