Thanks for reporting the ICE caused by the MSVC workaround I committed 
last week!  My apologizes!  I didn't know about this issue. The ICE did 
not occur when doing the unit tests (value_init_test.cpp).

Your patch:

Does the ICE also occur when using the destructor of the other base 
class, const_T_base?  If so, it would need a similar patch.

I will take a closer look later today, or otherwise tomorrow.  And I'll 
contact Fernando Cacciola, the creator and maintainer of the file.

Thanks again,
