--- Comment #6 from Peter Bergner <bergner at gcc dot gnu.org> 2012-11-19 22:07:55 UTC ---
Minimal test case (with minimal options) reduced from matmul_i1.i:

[bergner@igoo pr55381]$ cat pr55381.i 
void
foo (char * dest, char s, long ycount)
{
  long y;
  for (y = 0; y < ycount; y++)
    dest[y] = s;
}

I saw this using a 4.4.6 based compiler.
