            Bug ID: 57946
           Summary: internal compiler error: Segmentation fault in
                    int_fits_type_p
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: cas43 at cs dot stanford.edu

when compiling this program:

enum ENUM2 {  ENUM2_a = (enum ENUM2) 4,  ENUM2_b = 0x9FFFFFFF,  ENUM2_c =
0x100000000 };

like this:  g++ prog.cpp

I get this output:

prog.cpp:1:40: internal compiler error: Segmentation fault
   enum ENUM2 {  ENUM2_a = (enum ENUM2) 4,  ENUM2_b = 0x9FFFFFFF,  ENUM2_c =
0x100000000 };
