I think I know why: the same thing happened to me testing the pre-release
of 1.2.0 about a week ago, which I tracked down to a problem with R.dll and
Rbitmap.dll using different malloc's but the same free.

Please revert to the original R.dll for now.  The problem will go away (at
least on NT4, and the fix is still there) when rw1020 is released in a
couple of weeks or so.

Yes, it was.  The version of R (as distinct from the build) is unchanged.
