[Segmentation fault] error

[architectpianist]

Hi,
I'm having an uncalled-for error here. My app was working just fine, when I tweaked some of the algebra in an if statement and suddenly it gives me this error:

collect2: ld terminated with signal 11 [Segmentation fault]
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1

I know there are many reasons the second part could come up, but what does the [segmentation fault] mean?

Post the relevant code.

How can I? Basically the part I changed was this:

if (y < x + 26 && y < -x + 346)
		{
			if (x < 100)
			{
				point.x = 100;
				point.y = 126;
			}
			else if (x > 220)
			{
				point.x = 220;
				point.y = 126;
			}
			else 
			{
				point.y = 126;
			}
			touchPoint = point;
			currentLine = 1;
			NSLog(@"Current line: %i", currentLine);
			return;
		}

I don't know about you, but it seems pretty innocent to me. I've placed breakpoints all over, but nothing happens.
As I said, it was working fine until I just hit build and go, foolishly expecting my app to improve. Could you define "segmentation error" so I can see if anything rings a bell?

That looks like you caused a bug in the linker. I would recommended doing a "Clean All" and building again.

[architectpianist]

That didn't work either.

All fixed now. I've maybe had a week of experience with Xcode, so I just opened the Build menu and hit a random button. The button happened to be "Build and Analyze." As it turned out, there were two memory leaks, and after I fixed those, it worked perfectly.
Thanks for the input!
