According to your description, it seems that the issue you encountered
is only a symptom of some memory-management issue in your code: you've
got a damaged heap at the point where scoped_lock tries to allocate
memory. You can use MSVC heap debugging facilities to try and spot the
problem: http://msdn.microsoft.com/en-us/library/974tc9t1.aspx .
Besides, it worth checking that you never delete objects through a
pointer to base-case (directly or using smart-ptrs), if they don't
have virtual d-tor. This kind of bug ruins the heap immediately, but
it's quite hard to locate it using the above heap-debugging
techniques.
