Problem with dyn.load in R1.6.1 - R-help

Wed, Dec 11, 2002 9:27 PM #

I've been successfully using a dll via dyn.load() with R1.6.0 for
Windows, but when I try it under R1.6.1 it manages to crash the program
completely. Has there been a change in how R1.6.1 handles dynamic
loading? I couldn't spot any such changes in the documentation. This
problem occurred on two different machines, and both run the code under
R1.6.0 without a problem.

No deliberate change (it _was_ a patch release).  However, this is a not
uncommon occurence with code that is incorrect and corrupts memory or the
stack: sometimes you get away with it on some platforms.  We found that
with a version of the tseries package: it worked on 1.6.0 but not 1.6.1 on
Windows. (The problem was a .C call with one too few arguments.)

I don't see any main differences except of bug fixes. So I guess it's a
bug in the dll, which has not bit in R-1.6.0, however. 
Recompiling for the recent version of R is never a bad idea anyway.
