I believe that this is an issue with the evaluation of arguments: if you 
have a single expression the arguments are evaluated in an unspecified 
order - in this case the i++->str().length() gets evaluated before the 
i->length(), so i->length() is called on an end-of-sequence iterator (you 
should be able to confirm this by stepping through the code in your 
debugger).

This is perfectly standard C++ I'm afraid, and is not a library or compiler 
bug.

Hope this helps,

John.
