[xml] RE: Need help: My program trying to free

["Jones, Mark A (Mark)" <jones lucent com>]

If it helps at all, I'm currently using libxml2-2.6.5 on a Suse Linux platform.

Hi,

I'm getting a core dump after calling xmlFreeTextReader(reader).  Has anyone seen a problem like this before? 
 I show the piece of code that is dropping the core along with a few stack frames (gdb) from the core file.   
Any insight would be much appreciated.

Thanx,

M. Jones

Well what possibly could be in the code of a DLL that would prevent it from
being loaded into memory using LoadLibrary[Ex].  The dependencies, for one.
Perhaps the newer libxml2 is being built linked against a required library
that isn't present.  Perform a

 dumpbin /imports libxml2.dll

and compare the libraries it imports with the old working dll.
