[xml] xmlParseDoc in thread => Segfault

["Morten W. J." <morten newtec dk>]

Hello.

Using kernel 2.4, gcc version 3.2, libXml2 2.6.7, libc 2.3.1 and libpthread 
0.10 (Can that really be??) we have a threaded application running displaying 
a user interface on a framebuffer. The user interacts with a UI_thread and 
manipulates some settings which are read and stored as XML - hence the use of 
libXml2. The UI system typically has a "page" for each logically portion of 
the settings. "Pages" can call subpages and return to their own parent page. 
The root page runs in seperate thread (the UI_thread) and the main() routine 
loops infinte after spawning three threads.

Now, if we issue a xmlParseFile() ANY place within the UI_thread, that is 
AFTER a spawn, the application segfaults. If we comment out that single line 
the application runs without problems. 
If we issue a xmlParseFile() ANY place in the main (before or after spawning, 
in the main loop or before) there is no problem and the XML file gets parsed 
as expected.

It seems that :
xmlParseFile, in our case, cannot be called in a thread, although only that 
thread uses libXml(!!!, so it is probably not a thread problem in the common 
sense)

Is anybody having any input on that case?

regards, Morten

P.S.: The file being parsed exists and is well formed xml - tests fron within 
the code (open and read) confirms that.
