A Darwin-targeted clang may not crash with the original test case, because the
__asm() renaming on Darwin prepends
'\01' to the new function name. The following test case should crash on Darwin.
$ clang -S -emit-llvm -o - test.cpp
$ clang -S -femit-all-decls -emit-llvm -o - test.cpp
// test.cpp
extern "C" int printf(const char *, ...);
extern "C" {
void _ZN1SC2Ev(void) { }
}
struct S {
S() {
printf("S constructor\n");
};
} var;
