Build cc1 with checking disabled.
Then compile the following with ./cc1 -quiet -O2.
extern void abort (void) __attribute__ ((noreturn));
extern char *strcpy (char *__restrict __dest, __const char *__restrict __src);
int
foo (int aaa, int bbb)
{
static char buf[30];
const char *p;
switch (aaa)
{
case 10:
p = "hello";
break;
case 20:
p = "world";
break;
default:
abort ();
}
if (bbb)
{
strcpy (buf, "banana");
return 1;
}
strcpy (buf, p);
return 0;
}
I get "internal compiler error: Segmentation fault".
The testcase was reduced from i386.c.
