Summary: virtual keyword causes exception?

Initial Comment:
Adding "virtual" to a simple method causes the following exception to be raised:

"Program: A.exe
Exception: 0xC00000FD
Address: 00000000"


This happens both on the emulator I'm using (Microsoft DeviceEmulator Manager 9.0.21022.8) and on the real device (Intel XScale 400Mhz PXA 255).

The code being compiled is:

#include <iostream>


using std::cout;
using std::endl;


class Simple
{
public:
   Simple();
   virtual ~Simple();
};


Simple::Simple()
{
}

Simple::~Simple()
{
}


int
main()
{
   cout << "Strange?" << endl;
}


I'm compiling the code with

arm-wince-cegcc-g++ -o A.exe A.cpp

If I remove "virtual" from the destructor then the code runs without an exception. This happens for any method not just the destructor.

arm-wince-cegcc-g++ --version gives:

arm-wince-cegcc-g++ (GCC) 4.1.0

The test below is with your executable on my iPAQ 214 running WM 6.0.

pavilion: {121} rcp A.exe ipaq:/temp
pavilion: {122} rsh ipaq /temp/A.exe
Strange
pavilion: {123}

I've updated to 0.59.1 (and downloaded mpfr 2.4.1). Exactly the same thing
is happening. I've attached a tar ball of: the source, the output from
strace when compiling, the resultant .exe file and the build (go) script.
It's weird I have another app with a few thousand lines which all works
fine ... but as soon as I add "virtual" it fails.

I cannot reproduce this, but I'm using the gcc-4.4 based software.
Could you pick up the latest release (0.59.1) and try it ?
