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

Hi,
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, ...)
UseMethod("myf")
myf.default <- function(x, ...)
myf(x)
myf(1)
...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.
Cheers,
Rich
