No, I had got an impression he is complaining about something which he 
sees in his debugger only. The debuggers are known to sometimes display 
invalid or misleading information. I might be wrong, it is hard to say 
what OP meant by the phrase "while debugging".

The reported "crash" is basically an assert failure in a debug feature, 
so a proper Release build would obviously not have it. However, the OP 
did not talk anything about running a Release build, he just said 
"Program run from prompt works fine". I assumed that was the same Debug 
build, but I might be mistaken.
