           Summary: Segmentation Fault compiling templates with function
                    pointers
           Product: gcc
           Version: 4.2.1
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: cacoyi@gmail.com

Files needed to reproduce and report the bug.

When the source in the attached archive is compiled with:
    g++ -save-temps main.cpp

the output is:
    main.cpp: In member function ‘FTemplate<_Binary<FuncA, FuncB> >
    FTemplate<FuncA>::operator|(const FTemplate<FuncB>&) const [with int (*
FuncB)() = _Nullary, int (* FuncA)() = _Nullary]’:
    main.cpp:11: internal compiler error: Segmentation fault
    Please submit a full bug report,
    with preprocessed source if appropriate.
    See <URL:http://developer.apple.com/bugreporter> for instructions.

Admittedly this problem might be Apple specific, but it is probably worth
checking, as I understand it is the same code base and I'm not sure how
forthcoming Apple is with bugs.

GCC 4.2 is no longer maintained, you need to report it to Apple or use a more
recent, official FSF release.

4.4.5 gives

main.cpp: In function ‘int main(int, char* const*)’:
main.cpp:17: sorry, unimplemented: mangling template_id_expr

and 4.5.2 compiles it successfully
