Purify and xalan-c

[th...@ascentialsoftware.com]

Does anyone ran Purify on Xalan-c before?
I am purifying my code (which is using Xalan-c) on a windows 2000 machine
(using xalan-c 1.3).
I get a lot of FMM: Freeing mismatched memory (see a couple of example
above) which seems to be within Xalan code itself.

The purify documentation about FMM error is the following:

An FMM message indicates that the program is trying to free memory with the
wrong API call for that type of memory.

Purify reports a FMM message when the program allocates memory from one
family of APIs and then deallocates the memory from a mismatched family. For
example, a FMM message can occur when you use new to allocate memory and
free to free the memory. You can also get this message when you use one heap
to allocate memory and a wrong heap to deallocate the memory. 

Any ideas? Am I doing something wrong somewhere?

Thanks.

Thomas
