Hello.
I have the following multi thread related problem.
main(){
xmlInitParser();
//validationstuff
xmlParserCtxtPtr globalContext = xmlSchemaValidCtxtGetParserCtxt(ctxt);
}
threadFunction(){
xPathObjectPtr foos = xmlXPathEvalExpression ("foo", globalContext);
//read all the foos
}
(sorry I dont have the actual code here)
The program makes a lot of new threads and some of these segfault if
there are to many of them. So e.g. when I create 50 threads, approx. 10
of them segfault - the rest don't.
I first thought, I could fix this by using a globalDocPtr instead of
context and create a new context in each thread - but this will lead to
the segfaults.
I could reduce the problem to the xmlXPathEvalExpression call (since if
I return before, everything wents fine).
Did I use the API wrong or what is the problem (at least as you can say
based on the piece of code)?
Regards,
Oliver
