[cfe-dev] terminate called without an active exception

[Scott Parlane]

Hi,

Given the following (invalid, type_5 is not defined) code.

// BEGIN
typedef enum { type_1 , type_2 , type_3 , type_4 } types;

_Bool testfunc(types t){
        switch(t)
        {
                case type_1:
                case type_2:
                case type_5:{
                        return true;
                } break;
                default: {
                        return false;
                }
        }
}
// END

clang called as follows
 # clang -c -emit-llvm test.c -o test.bc

results in
