Core dump on sapply misuse

I hope this is the appropriate place to post this request.
I am getting a core dump in an application of sapply. A
simplified example is the following. Because simplify=TRUE
is the default for sapply and tapply, the following works
x <- 1:5; sapply(x,list)
but the following dumps core with an access violation
x <- 1:5; myf <- function(x) list(x,x); sapply(x,myf)
I am running R version 0.63.1 under Windows NT 4.00 (p.s.
and am also experiencing the 'impossible to access
clipboard' problem with graphics under NT but not under
Could a gentler message be encoded (e.g. a check after the
call to lapply) to inform the user that sapply (and tapply)
is being abused? A core dump seems a rather harsh caveat
