             Bug #: 51826
           Summary: internal compiler error: in convert_nontype_argument,
                    at cp/pt.c:5408
    Classification: Unclassified
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: just.serejko@gmail.com


The following code

template<int n> 
struct bug {
    static const int value = 0;
};

int main(int argc, char **argv) {

    int x = bug<(int)"123">::value;
    return 0;
}

gives me this on 4.6.1 (MinGW):

template_mess.cpp: In function 'int main(int, char**)':
template_mess.cpp:8:24: internal compiler error: in convert_nontype_argument,
