This sounds like a problem with variable and memory initialisation etc. When run within VS you operate in a clean sandbox where all the memory is nicely managed and initialised by VS. In the debug versions, numeric variables and pointers are initialized to 0 and NULL whilst in the release versions, those numeric variables and pointers are any random value so you could have unexpected results.
google "debug v release" for more info on this - plenty of people have been bitten. Also http://www.codeproject.com/KB/debug/releasemode.aspx contains some good info. I might be wide of the mark but it's the best I can manage based on your first 2 sentences.
