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

Message:
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 ?
