From 5e6c595e9d698caf23ae68d38b9cab30ff9c9b94 Mon Sep 17 00:00:00 2001 From: Stephan Bergmann Date: Thu, 20 Sep 2012 15:40:30 +0200 Subject: Do not call xmlCleanupParser from liblangtag Despite its name, it is a cleanup function for libxml2 that must only be called when the process as a whole no longer needs libxml2. Calling it from a library like liblangtag is not appropriate (just like liblangtag does not call xmlInitParser, either). In LibreOffice, this caused confusion about pthread keys for thread-local storage (xmlCleanupParser calls pthread_key_delete, but apparently if libxml2 is later used by unrelated code in LibreOffice again, it still uses the stale key, and if that key is now reused via an unrelated pthread_key_create, arbitrary crashes happen during thread termination in pthread's __nptl_deallocate_tsd).
