Agnes:
I don't think the Dr. Watson dump is going to help you much. Do you have any clue as to what your code was trying to do when it crashed?
If you search this forum for "debug release crash" or "release version crash" or similar phrases, you'll find that this is a pretty common question. Look through the other posts you find here to see if anything is applicable to you.
The debug version does some things like padding variables so you can sometimes overrun your declared variable space without overwriting the next variable. In the release version, the variables are packed, so if you overrun one, you are overwriting another. Just one possible difference.
You can do some things in your release code to see where things get lost, like temporarily using printf statements at the start and end of different sections of your code to try to identify the failing line of code.
Look through other threads to find other ideas.
