[Rcpp-devel] V8 crashes on 32bit windows when built with new Rtools

Why would posix be enabled for a Windows target?

Yes, that doesn't seem to help.

I have a suspicion now. I have seen this behavior before when linking
libraries on windows that were built with different threading models.
Based on gcc -v, the old rtools (and hence my v8 static libs) use win32
threading, whereas the new rtools has been built with
--enable-threads=posix.
The scripts are on CRAN, if you want to try modifying them.  However, if
the scripts aren't satisfactory very soon, I'll just go back to the
previous Rtools.
