exception problem

[chris schaefer <ch...@seacoms.com>]

Hello:
   In my code I to create, delete and then recreate  a class which uses
Xerces.  ( there is only ever ONE instance at a time )
I'm running into an exception thrown on the second usage of the class:

My constructor/destructor has the  XMLPlatformUtils::Initialize(); and
XMLPlatformUtils::Terminate();  calls.

Obiously there is some problem with a mutex here.  Does anyone have ANY idea
what this might be about?  I suspect
that I'm doing something wrong, but I have no idea what.   For reference this
is 1_3_0 running on RH7.0 linux.

The last line of my code ConfigManager.C:108   is:
pDOMparser = new DOMParser;

Since I'm expecting xerces to do it's garbage collecting thing, I never delete
this parser, even on reuse of the pointer, and
not in the detructor either.  is that correct?
