[Bug target/18649] terminate called after throwing - IOT/Abort trap (core dumped)

If I compile and link the example in my last comment (shown below) with
-pthread, it will always run. If I don't it will always core dump. This is with
g++ 3.4.3 on AIX 5.2. Does anyone know if the same program compiled with g++
3.3.3 will behave the same way on AIX 5.2 ? (i.e. run okay when compiled and
linked with -pthread but abort otherwise ?)

bluetrance:13391$ cat a2.cpp
void mycall()
{
        throw 0;
}
bluetrance:13391$ cat a1.cpp
                                                                                 
extern void mycall();
 
int main()
{
        try {
                mycall();
        } catch (int i) {
                return i;
        }
        return 1;
}
 
 
bluetrance:13391$ g++ -fPIC -DPIC -shared -pthread -o liba2.a a2.cpp
bluetrance:13391$ g++ -fPIC -DPIC -o a1 a1.cpp -pthread -L. -la2
