Presumably the call to erase is inadvertently missing ever since that 
call to remove_if got introduced in 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=1b059829bc6698c15c6bb5459a61348ac56ffda5> 
"Added container to store global anonymous db ranges."

AnonDBs (sc/inc/dbdata.hxx) looks like it is a thin wrapper around a 
boost::ptr_vector, exporting just those member functions of the 
underlying ptr_vector class that are used by client code, plus some 
AnonDBs-specific functions, which arguably is not the most 
maintenance-friendly approach.

So looks like AnonDBs should also export the underlying ptr_vector's 
ranged erase.
