Hi,

we just ran into a bug that seems to be a show-
stopper for us.
We are making a plugin (DLL) for some application.
It is loaded from the app (presumably) using
'LoadLibrary()'. Then code in the DLL is executed.
Sometimes, this implies calls to 'std::issspace()'
which in turn will call 'locale::facet::_Register()'
to register a locale with the C++ runtime. Later
on, the DLL will be unloaded. However, the run-
time only treis to un-register the facet when the
/process/ terminates. At this time the DLL is long
gone and the app thus crashes at shutdown.

A search across the KB (using the term "register
locale crash") didn't come up with something.
Google did find a reference to what appears to be
this bug. (Search for the string "DINKUMWARE BUG"
on http://cvs.sourceforge.net/viewcvs.py/filezilla/FileZilla%20Server/source/misc/StdString.h?rev=1.4)

Is there any fix for this? We use a few 3rd-party
libs that call locale-dependend functions which
will trigger this bug. It would be a huge problem
if we had to go through all this code and try to
understand it in order to fix the problem.

TIA,

Schobi
