I tried putting xmlInitParser() at the start of my program and called xmlCleanUpParser in the process cleanup function It gave me a huge improvement in memory leaks. valgrind use to show me lot of memory leak in xmlNewMutex etc.. now I do not have them at all.
You are right the xmlCleanUpParser which I use to call in my parsing function might be the cause of the crash in xmlFreeDoc. I will let you know once i run the test. Thanks a lot
I had tried the xmllint --version command before, I did not find any information related to threads. When issued the xmllint --version command i got following output
[EMAIL PROTECTED] libxml2-2.6.10]# /usr/local/bin/xmllint --version
/usr/local/bin/xmllint: using libxml version 20610
compiled with: DTDValid FTP HTTP HTML C14N Catalog XPath XPointer XInclude Iconv Unicode Regexps Automata Schemas
I see your libxml2 version as 2.6.24 was this support not available 2.6.10?
this time i had compiled libxml2 as follows:
./configure --prefix=/usr/local --without-python --with-threads
make
make install
make tests
Thanks,

IIRC, xmlInitParser() and xmlCleanupParser() call those threading
specific functions. Just look at the code of xmlInitParser() & co.,
and you'll see what they actually do; the easiest way to clarify
such things.

I think "xmllint --version" could be the easiest way to query this:
[EMAIL PROTECTED]:/data/home/kbuchcik/gnomecvs/libxslt$ xmllint --version
xmllint: using libxml version 20624-CVS2779
compiled with: **Threads** Tree Output Push Reader Patterns Writer
SAXv1 FTP HTTP DTDValid HTML Legacy C14N Catalog XPath XPointer XInclude
Iconv ISO8859X Unicode Regexps Automata Expr Schemas Schematron Modules
Debug MemDebug
But please avoid writing privately only to me. The mailing list
is intended for such questions, and you'll reach a broaded audience
than just me. I'm not even an expert for Libxml2's multithreading
issues.
