issue with XSLT [0.8.x]

[Kuramoto Eiji]

I think it may be a bug.

well-formed status (ctx->ctxt->wellFormed) should check and save
before free xmlParserCtxtPtr. like this,

 } It seems to be similar to an issue raised on the Russian maillinglist (http://www.lexa.ru/nginx-ru/msg25325.html ), although I'm not using FastCGI but just use static XML files as input for the XSLT-engine.
