I'm having a hard-time debugging a local variable. I'm running gcc 4.2, XCode 3.2.4, base SDK Mac OS 10.5, and Objective-C++ in Debug-Mode.
Here's the issue. I'm working on trying to understand some code and it goes like this:
#define MAX4D 500
...
NSMutableArray *viewerPix[ MAX4D ];
When I hover over it during debug (pause on the line before and after) I get this
Unable to access variable "viewerPix"
Unable to access variable "viewerPix"
Unable to access variable "viewerPix"
...
repeated until I kill the application. What would cause this? I've tried setting it to a lower number... but to no avail. Even after I actually set the C-Array:
viewerPix[0] = [[NSMutableArray alloc] initWithCapacity:0];
I still get the same repeated error message.
However, if I don't mouse-over the value (or debug) it "appears" to run fine, even doing stuff like:
[viewerPix[0] addObject: dcmPix];
if( [viewerPix[0] count] != [loadList count])...
but if I debug after those steps, it crashes just like before. Here are my build settings:

I don't know what else to say. Let me know what more information is needed, because I'm at a loss. There's also no 'build' tab when I get-info on the .mm file. Just General, Target, Comments (some helps I checked said to remove file-specific tags).
Should I initialize that c-array to nil? I can't just do.. array[500] = {nil}; right? that's C#?
I was using LLVM and Clang 1.5, but I switched to GCC 4.2 since I wasn't getting any local symbols. Am I missing something??
