Signal errors - cocoa app

Question

Hi Everyone,
I was wondering if anyone could point me in the way of any kind of documentation regarding signal errors in xcode. I build my application and sometimes it runs fine while other times I get errors such as signal 5,10, and 11. I don't change any of the code and I just run the application a few times and it just crashes frequently.
I can't really post the code cause i have a whole bunch of classes and stuff but maybe someone could try pointing me in the right direction. I don't know if this helps or not but i've noticed, when running in debug mode, that in at least one of my classes the awakefromnib function is called more than once.
I would really appreciate any help.
Thanks

hey guys,
thanks for all the responses.
I have narrowed down the problem to these functions:
(note field is an IBOutlet NSBox subview initializedd in the NIB file)
- (void)awakeFromNib
[self initializeField];
- (void)initializeField
int i;
int j;
int upperRightBeginX = 8;
int upperRightBeginY = 280;
int addToX = 0;
int addToY = 0;
for (i = 0; i < width; i++)
for (j = 0; j < height; j++)
NSRect frame;
frame.origin = NSMakePoint(upperRightBeginX + addToX, upperRightBeginY - addToY);
frame.size = NSMakeSize(30, 30);
NDButtonOverrider *aButton = [[NDButtonOverrider alloc] initWithFrame:frame];
[field addSubview:aButton positioned:NSWindowAbove relativeTo:nil];
[aButton setImagePosition:NSImageOnly];
[aButton setImage:[NSImage imageNamed:@"gymFloor2"]];
[aButton setIndexInArray:[cells count]];
[aButton setTheMatrix:self];
[cells addObject:aButton];
[aButton release];
addToY += 30;
addToY = 0;
addToX += 30;
srand (time(NULL));
[self setCells];
- (void) setCells
int totalNumberOfCells = height * width;
int i = 0;
while (i < numberOfM)
int cell = rand() % totalNumberOfCells;
NDButtonOverrider *button = (NDButtonOverrider *)[cells objectAtIndex:cell];
if (![button isM]) {
[button setIsM:YES];
i++;
[button release];
for reference purposes:
this function is in NDButtonOverrider
- (void)setTheMatrix:(NDMatrix *)matrix
[matrix retain];
theMatrix = matrix;
I honestly don't know what's going on. I've been at this for hours now. If anyone has some idea of what's going on please let me know.
Thanks for a all the help.
