There is no source code available for the current location?!

Hi, I've spent several hours on this and I can't figure out what's wrong Please help.

Edit 2: I tried everything in Dev-C++ and there were no errors (I was originally using VC++), so it's a debugger problem :/ I still don't know how to solve it...
Edit: Here's a smaller program that I thought was pretty straightforward that still gives me the same error when debugging

Code:

#include<iostream>
using namespace std;

int main() {
	int m=4;
	int ** Rows;
	Rows = new int * [m];
	return 0;
}

Code:

#include<iostream>
using namespace std;

struct Node {
	int row;
	int col;
	int value;
	Node * next_in_col;
	Node * next_in_row;
};

int main() {
	int m, n;
	cin >> m >> n;
	Node * * Rows;
	Rows = new Node * [m];
}

When I debug I get this error message:
"There is no source code available for the current location.
OK / Show Disassembly"

--- f:\dd\vctools\crt_bld\self_x86\crt\src\newaop.cpp --------------------------
002C14C0 mov edi,edi
002C14C2 push ebp
002C14C3 mov ebp,esp

002C14C8 push eax
002C14C9 call operator new (2C1186h)
002C14CE add esp,4
002C14D1 pop ebp
002C14D2 ret

(the yellow arrow points to the first line: "mov edi,edi")

Also, I know it runs, but when I put it in a larger program it crashes miserably

If it's any consolation, both those snippets compile and run fine for me (g++ on linux), I don't think you are doing anything wrong.

Try it with malloc:

Code:

#include <cstdlib>
[...]
	Rows = (Node**)malloc(m*sizeof(Node));

Make sure you're compiling with debug flag. I don't know if Dev-C++ automatically switches to the debug target when you choose to run the debugger or not, so check the build options or whatever pertains to that.

I think Dev-C++ comes with a really old version of MinGW, too, so you might consider getting the new version of that.

You normally get that when working with DLLs that you do not have the source for - otherwise called release candidates. Not sure why you are getting that with this particular project.

Maybe try parenthesis? like this:

Rows = new (Node*)[m]

If not, I am out of idears!
