that "base" returns a reverse iterator instead. This is not specific 
with ptr_vector. All the pointer containers seem to have this problem.

Indeed they have. Thay always return the iterators with void* 
value_type. It's my oversigt.

I haven't tried it, but to get an iterator given a reverse iterator, one 
should be able to do

iterator i( ri.base().base() );

Looks pretty ugly.
