Haven't had time to investigate much yet (and probably won't for a

against that Mesa version (the whole lot), the server blows up right
away when launching glxinfo or glxgears.
The latest log I got (with glxgears) shows this backtrace:
It isn't clear from the stack trace what went wrong, but I've just
checked in a patch which fixes a few issues: GLcore needs to build with
TLS settings matching glx, the ARGB visual is now marked as
non-conformant, and there was a problem with freeing a mesa buffer even
if it never got allocated.
