[Bug c++/34953] New: ICC on destructor + noreturn-function at -O3

[bisqwit at iki dot fi]

This code crashes GCC versions 4.1.2, 4.1.3, and 4.2.3, when compiled using the
-O3 option.


void B_CLEAR(void* ret);
void B_NeverReturns(void* ret) __attribute__((noreturn));

int main()
{
    const struct AutoErrPop { ~AutoErrPop() { } } AutoErrPopper = { };
    B_NeverReturns(0);
}

void B_NeverReturns(void* ret)
{
    B_CLEAR(ret); /* Never returns (does a setjmp/goto) */
}

Tested on x86_64 and i386. To reproduce: g++ a.cc -O3

Expected result:
a.cc:4: internal compiler error: Segmentation fault
