Well, this is not very nice. You should do some homework before asking the question. You should try to create a possibly minimal code sample to reproduce this message and post it in your question. Some can guess what it was, but why? Why looking at the error message not having the code which caused that message? After all, you are the one who is the most interested in a correct answer.

Why not: 1. learn to use copy and paste properly,
2. show the line of code that causes the error,
3. use <pre> tags around code lines

Besides, with the different return types, your cast cannot work as the stack could get messed up.

See this link for similar problem and solution.
