           Summary: DWARF-2 output mishandles large enums
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: debug
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: drow at gcc dot gnu dot org
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: i386-pc-linux-gnu
  GCC host triplet: i386-pc-linux-gnu
GCC target triplet: i386-pc-linux-gnu

Given this line:
enum e {I, J=(unsigned)0xffffffff} e = J;

Compiled with -gdwarf-2, we get:
 <2><2f>: Abbrev Number: 3 (DW_TAG_enumerator)
     DW_AT_name        : I
     DW_AT_const_value : 0
 <2><33>: Abbrev Number: 4 (DW_TAG_enumerator)
     DW_AT_name        : J

There is no DW_AT_const_value for J, so GDB can not figure out
the value of J.
