[lxml-dev] thread-related crash when using xslt

Hi there, Attached is a small tarball that demonstrates code that crashes when the code is run in a thread but doesn't crash when it is run stand-alone. I isolated the specific XSLT + XML combination that seems to trigger this crash. I suspect it has to do with passing an XSLT object to a thread. I run this with lxml 2.1.5 in Python 2.4, libxml2 2.6.32 and libxslt 1.1.24 By the way, the FAQ implies that passing an XSLT object into a thread will slow things down (probably as the XSLT would be re-interpreted). Is that still true in the current codebase? I had the impression from previous discussions that this would change. Regards, Martijn
