I think the gist is that the recovered pointer itself is somehow NULL:
tree current_fn_decl = gimple_call_fndecl(stmt);
if (!current_fn_decl) return false; // *this won't execute*
struct function* fs0 = DECL_STRUCT_FUNCTION(current_fn_decl);
if (!fs0) {
std::cerr << "error pointer ! " << get_name(fs0->decl) <<
std::endl; // *this will execute*
}
