Re: [xml] Strange segmentation fault on Win32 with htmlCreatePushParserCtxt

Ok,

I've narrowed it down to the use of __declspec(thread) in the declaration
of the two variables tlstate and tlstate_inited.

If I remove the declspec everything seems to work fine. My question now
is, what is the reason for using TLS?
