[xml] Threads and statically linked libxml2 in a plugin

[Gregoire Banderet <Gregoire Banderet ge com>]

Hello,

I use the libxml2 in my multi-threaded app (let's say MYAPP).
MYAPP runs on Linux-ppc and links libxml2 statically (libxml2.a).
MYAPP is able to load plugins, and one of these plugins uses libxml2 
too. This plugin also links statically libxml2.

My question: Should I call xmlInitParser() and xmlCleanupParser() in the 
plugin code?

The doc says that xmlInitParser() should be called once per process, so 
the answer should be "no".
But as the code of libxml2 is duplicated in the plugin (because of 
static link), will all the libxml2 variables initialized?

Note that if I do the init/cleanup calls in the plugin, the thread dumps 
core on pthred_exit. The crash is in xmlFreeGlobalState(). I guess 
because of the pthread_key_create(&globalkey, xmlFreeGlobalState) done 
in xmlOnceInit(void).
It does not crash on Windows (no use of Posix threads).

Thanks for you help,
Greg

PS: I can't use libxml2 as a shared lib.
