Description Andrew Pinski 2006-11-22 19:23:30 UTC 
The code from libgfortran ICEs:
extern const char *__ctype_ptr;
parse_real (unsigned char c)
{
  if ((__ctype_ptr[c]&04) &&c != '.')
   unget_char ( c);
}
---------------------------------
t.c: In function 'parse_real':
t.c:6: internal compiler error: in simplify_subreg, at simplify-rtx.c:4470
