efriedma added a comment. We usually prefer to generate error messages for incorrect parameters to builtins in SemaChecking.cpp.
I don't think there's really an infinite loop here. The parameter to __builtin_frame_address is an unsigned integer; values greater than 0x7FFFFFFU aren't special. The reason it takes a very long time is that we try to unroll the implied loop; generating an object file with four billion load instructions takes essentially forever. We could impose a smaller limit, but it would be sort of arbitrary.
