debugging - iPhone development- where can I get a list of all signals received by apps and what they mean -

My app crashes at a special point when testing on the phone The console shows this message

  Tuesday Jan 27 15:47:14 Unknown Springboard [22] & lt; Warning & gt;: Application & lt; SBApplication: 0x3f26180 & gt; Activate Com.myprof.test: deactivate: Unexpected exit with the signal 10: Just error  

Where can I find a list with the meaning of all these signals? Thank you.

Edit: Is there a way to know why the error is? According to the Signal Man page, the signal 10 is the error (which is BTW, is clear from the error), but what does it mean and how do I delete it?

Thanks again

A just error means that you can access the memory Trying to contradict the fault of a division, which means that you are reaching memory which is not for you in any way, you probably have a stray indicator.

Try using the memory allocation debugger in XCode (Guard Malloc). It will run only in the simulator and makes things very slow, but I find it very useful.
