[Bug c/22311] [4.0/4.1 Regression] internal compiler error: in c_common_type (-fshort-enums)

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-07-05 16:04 -------
Confirmed, reduced testcase:
typedef enum {
  IssueItemFlag_Discard = 0x1
} IssueItemFlag;
void
BlockRegion_findInvariants(IssueItemFlag invariant, unsigned char a)
{
  a |= invariant;
}

Only -fshort-enums is needed to reproduce the bug.
