I have this piece of code. This is called once every frame
[source lang="cpp"] //While there is a message to deliver
while(<=currentTime && !messageQueue.empty())
//deliver the message>handleMessage(;
//delete the message

This works fine in release, but when I run in debug mode, I soon get an assertion failure: "Debug Assertion Failed! vector iterator not dereferencable" Edited by lride

You should put the !messageQueue.empty() test before you attempt to dereference top(), in case the queue actually is empty which would mean that is trying to dereference end() iterator.
