Are you referring to a debug build? If so, why do you care about it?
What compiler?

1.34 introduced a macro for tuning all the exceptions into asserts.

Well, there has been some indications that the void* implementation
leads to slightly slower code. OTOH, the void* implementation was made 
exactly to avoid bloat on compilers that generate new code for every T*.
