I can't evaluate any valuable in the debug console.

Issue Type: Bug

I tried to debug a C++ program and had set a breakpoint. After it paused at the breakpoint, I type "s"(which is a "char s[100]" type) in the debug console and saw this:

Stopping due to fatal error: ArgumentException: An item with the same key has already been added. Key: (Microsoft.MIDebugEngine.AD7StackFrame, s)

example program:

#include <cstdio>
int main(){
	char s[100]="12345";
	printf("%s\n",s);
	return 0; // breakpoint was at this line
}

Complie and debug it, type "s" and press Enter in the debug console.

Expected behaviour:
Output the value of s(v [100])

In fact, the output is:

v[100]
Stopping due to fatal error: ArgumentException: An item with the same key has already been added. Key: (Microsoft.MIDebugEngine.AD7StackFrame, s)

and it really stopped.

Hi, this extension just uses Mircosoft's official C/C++ extension for debugging.
So if there is any bug you should raise an issue there.
However, maybe I can help you.
Are you using GCC, Clang, or MSVC Compiler?
Can you send a screenshot of your described use case?
