I've been wondering why the following trivial code produces a segmentation fault when returning from main():

//Produces "Error while dumping state (probably corrupted stack); Segmentation fault"

#include <iostream>
#include <fstream>
#include <vector>
using namespace std;

class Test
{
    vector<int> numbers;
};

int main()
{
    Test a;
    ifstream infile;

    cout << "Last statement..." << endl; // this gets executed
    return 0;
}

Interestingly, 1) if only one of the two variables is declared, I don't get the error, 2) if I declare a vector variable instead of an object with a vector member, everything's fine, 3) if I declare an ofstream instead of an ifstream, again, everything works fine. Something appears to be wrong with this specific combination...

Could this be a compiler bug? I use gcc version 3.4.4 with cygwin.

Thanks for the tips in advance.
