R devel - Dec 2000 - crash using bmp() on windows with Rdll2010 (PR#756)

A few weeks ago I have updated R-1.1.1 for Windows with the fixed R.dll
(Rdll2010.zip) for Win2k from CRAN.
(I have used the same version of R from WinNT4 *and* Win2k for some
time.)

Now I tried to produce a bitmap, but R crashes (WinNT4):
 bmp("bitmap.bmp")
 plot(1:10)
 dev.off() ## crash!

That does not happen with the original R.dll from R-1.1.1 (15 Aug 2000).

I cannot test on Win2k, because I removed Win2k from my box in the last
week. 
The Rdll2010 reports the same version as the original R.dll (15 Aug
2000). That's not intended, I think?

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.
