Probable duplicate seen downstream here (compiling "tgif"):
https://bugzilla.redhat.com/show_bug.cgi?id=1553505
I reduced it to:
# cat rhbz1553505.c
struct NamesRec {
char inbuf[512];
char dir_name[256 + 1];
char name[256 + 1];
};
static struct NamesRec namesInfo;
static void ParseFileName(char *FullName, char *DirName, char *Name)
{
int i, len;
len = __builtin_strlen(FullName);
__builtin_strcpy(DirName, FullName);
for (i = len - 1; i >= 0; i--) {
if (DirName[i] == '/') {
__builtin_strcpy(Name, &(DirName[i + 1]));
}
}
}
void BackUpOneWord(void)
{
struct NamesRec *pni = (&namesInfo);
ParseFileName(pni->inbuf, pni->dir_name, pni->name);
}
# gcc -O2 -Wrestrict rhbz1553505.c
during GIMPLE pass: strlen
rhbz1553505.c: In function ‘BackUpOneWord’:
rhbz1553505.c:18:6: internal compiler error: Segmentation fault
void BackUpOneWord(void)
^~~~~~~~~~~~~
(etc; looks like the same backtrace)
