Unfortunately, some people are still experiencing this problem even
after they've upgraded to a recent version of R release/devel.

There was definitely a PROTECT/UNPROTECT bug in the reg.finalizer() code,
and that bug has been fixed in R release/devel one month ago. After
this fix, I did some (light) testing and was not able to get the
annoying 'formal argument "envir" matched by multiple actual arguments'
error anymore, so I concluded that the issue was solved...

Kasper contacted me off-list recently because he was still getting the
error. With the details he provided, I was able to isolate another
PROTECT/UNPROTECT issue, but this time in the setGeneric/setMethod
C code (methods package). I've sent a bug report to R-devel but haven't
heard back from them yet:

I'll post here again as soon as I have something new.

Thanks for your patience with this issue!

Cheers,
H.
