[Bug c/25183] [4.0/4.1/4.2 Regression] internal compiler error triggered by overflow in constant expression

[pinskia at gcc dot gnu dot org]

------- Comment #3 from pinskia at gcc dot gnu dot org  2005-11-30 16:17 -------
Confirmed, reduced testcase:
enum err {
  err_IO = 0x8a450000,
  err_NM,
  err_EOF,
  err_SE,
  err_PT,
};
static enum err E_;
int error()
{
  switch (E_) {
    case err_IO : break;
    case err_NM : break;
    case err_EOF : break;
    case err_SE : break;
    case err_PT : break;
    default : return 0;
  }
}
