Problem with dyn.load in R1.6.1

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.
