[Rd] Infinite recursion in S3 methods crashes R on windows (related to PR#8203?)

Infinite recursion in S3 methods seem to crash R on Windows 2000 (R terminating with the ("Rgui.exe has generated errors...") message, rather than throwing an error. This happens with both Rgui and Rterm.

The following toy example triggers this: myf <- function(x, ...)

myf.default <- function(x, ...)

...R crashes...

Which I would expect to terminate with the usual "evaluation nested too deeply: infinite recursion" or protect stack overflow message.

This may be related to the reported bug 8203 - apologies if this has been fixed. I couldn't find specific mention of this in the NEWS file.

This does not happen on R 2.1.0 on Windows 2000 (same machine), or on R 2.2.0 on Linux. R/Machine version below.
