GCC 3.3 exception problem

["Gary Hughes" <geh at itga dot com dot au>]

Hi,

I have just download and built GCC 3.3 and C++ exceptions are causing
problems. Whenever I throw and exception my program aborts and dumps core. I
get the same behaviour on both Solaris 2.6 and 2.8.

The following program is an example.

#include <iostream>

int main()
{
    try
    {
        throw 5;
    }
    catch(int i)
    {
        std::cerr << i << std::endl;
    }
    catch(...)
    {
        std::cerr << "unknown" << std::endl;
    }

    return 0;
}

Here is the stack trace

(gdb) bt

Here is the configuration of gcc.

Is this a known problem or have I done something obviously wrong? I did some
googling and had a look in the mail list archives however I can't find
anything similar.
