hm, it might be a problem with concurrent access to the extension
handling, but this is just a guess. I'll take a look at the extension
handling from that angle.

I imagine it would be possible to paper over the problem, by either
finding out how to disable the range checks in the MS STL or use the
attached patch (but that might disable an extension, although it is
actually available), to get things going.
