Hello.

Did you do any XML parsing in Emacs before this crash?
There is a well known bug in xmlCleanupParser that destroys thread 
specific storage, see: 
http://lists.fedoraproject.org/pipermail/devel/2010-January/129117.html.

Does emacs suffer from this issue?

I think so, xmlCleanupParser is called by parse_region every time it parses 
successfully.  According to the bug and documentation, xmlCleanupParser shall 
be called only when you are sure no more xml calls will be made by the 
program.  It is suggested to do this just before exit in case you are not 
sure, to avoid that valgrind (and other memory debuggers) report memory leaks.

Hi.

It might be another library that emacs links in that calls xmlCleanupParser.
Can you start it in the debugger and put a breakpoint on xmlCleanupParser and 
see if it hets called?

Does this happen all the time or just sometimes?

Ok; I've now removed the call to xmlCleanupParser from the parsing
function, and moved it to shut_down_emacs.  That's the right place,
isn't it?

Anyway, has it been confirmed that XML parsing has anything to do with
this crash?

No, it is just the prime suspect.
