Confirmed.

Here's something slightly smaller that crashed when compiled with "g++ -O"
(regardless of using -funit-at-a-time or -fno-unit-at-a-time).

==================================================
int foo();
inline void bar() throw() {}

struct A
{
    A()
    {
        int i=foo();

        if (i)
        {
            try         { while (i) ; }
            catch (...) { while (true) ; }
        }
        i=0;
    }
};

struct B
{
    ~B() { while (true) ; }
};

A* p;

void baz()
{
    p=new A;
    B b;
    bar();
}
==================================================
