Re: [xml] xmlReadFile(...) crashing on 2nd time around

[Andrew Hartley <andrew hartley bcs org uk>]

Thank you Martin, that works.

However, I am intrigued to know why this causes an issue.

My program consists of:

   (1)  Main program is written in Borland C++ v5.01
   (2)  Regular MFC DLL

The program in (1) loads the DLL in (2) by calling LoadLibrary etc... the
DLL has Libxml2 statically linked.

The program (1) called loaded and unloaded the DLL in (2) which in turn
loaded an XML with Libxml2.  With the call into xmlCleanupParser() the 1st
call to the DLL was OK but if the program loaded the DLL again in the same
session a crash resulted.  Now that I have taken out the call into
xmlCleanupParser() I no longer get the crash.

I would appreciate if anyone can let me know why I no longer get the crash. 
Do I need to call anything other than xmlCleanupParser().  Of course I am
freeing the xmlDocPtr and contexts correctly.
