This looks like the type of memory leak that occurs after a call to:

typeid(MyType).name();

see this article for a full explanation:

Personally speaking I find these leaks obscure real leaks in my code. 
You can solve this by disabling heap checking, then allocating 
typeid(MyType).name() then re-enabling heap checking.
