------- Comment #3 from pinskia at gcc dot gnu dot org  2009-06-21 23:42 -------
Confirmed, reduced testcase:
void f(int, int);
int g(int);
extern char errortext[300];

void ParseMatrix (void)
{
  char items[1000];
  extern int item;
  int range;
  int i, j, type, cnt;
  for (i=0; i<item; i+=cnt)
  {
    cnt=1;
    if (!type)
      range = 16;
    else
      range = 64;
    for(j=0; j<range; j++)
      if (1 != g (items[i+cnt+j]))
        f (items[i], items[i+cnt+j]);
    cnt+=j;
  }
}
