Hi,
I was pasting a copying a class member initializer list into some function block and got this exception and call stack:
---------------------------
msdev.exe - Application Error
---------------------------
The exception Breakpoint
A breakpoint has been reached.
(0x80000003) occurred in the application at location 0x1edbab96.
Click on OK to terminate the program
Click on CANCEL to debug the program
---------------------------
OK Cancel

VA_X.dll!1edcb05b()
VA_X.dll!1ed6da7d()
VA_X.dll!1edbfe50()
VA_X.dll!1edbdc3d()
The copy and paste was similar to this:
// _a1, _a2, _b1 and _b2 are of type short
A::A(long a, long b) : _a1(a >> 16), _a2(a & 0xffff), _b1(b >> 16), _b2(b & 0xffff)
{
}
void A::Set(long a, long b)
{
_a1 = a;
// I copied the above initializer from "a >> 16" up to "b & 0xffff" into the clipboard Ctrl+C
// I selected the a above without ; and pasted the clipboard
// I could see the resulting
// _a1 = a >> 16), _a2(a & 0xffff), _b1(b >> 16), _b2(b & 0xffff;
// I tried to reposition the cursor with the mouse bit VC++ hang and than I got the above exception
}
I hope that helps to trace the problem,

BTW - this is reproduceable with the above code sample. I created a simple console app and replaced the created code with this one:
### START OF FILE ###
// conVC6.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
class A
{
public:
A(long a, long b);
void Set(long a, long b);
private:
short _a1, _a2, _b1, _b2;
};
// _a1, _a2, _b1 and _b2 are of type short
A::A(long a, long b) : _a1(a >> 16), _a2(a & 0xffff), _b1(b >> 16), _b2(b & 0xffff)
{
}
void A::Set(long a, long b)
{
_a1 = a;
// I copied the above initializer from "a >> 16" up to "b & 0xffff" into the clipboard Ctrl+C
// I selected the a above without ; and pasted the clipboard
// I could see the resulting
// _a1 = a >> 16), _a2(a & 0xffff), _b1(b >> 16), _b2(b & 0xffff;
// I tried to reposition the cursor with the mouse bit VC++ hang and than I got the above exception
}
int main(int argc, char* argv[])
{
return 0;
}
### END OF FILE ###
I followed my copy&paste comments in the Set function and ended with the same exception dialog.
HTH,
