Hi, people. Wandering in R archives, and seeing the message attached below, I noticed that:

   mapply(rep,times=1:4, MoreArgs=42)

still segfaults on R 2.2.0, and thought I should be a good citizen and report it, even if I do not have an actual problem with this. :-)

> version

platform i686-pc-linux-gnu

arch     i686

svn rev  35749            
language R                

(By the way, in the output of "R.version", should all the spurious whitespace be kept at end of lines?)

I get this too on the released version.  I guess the problem is that the 
value passed to MoreArgs is not a list.  Maybe,

mapply(rep, times = 1:4, MoreArgs = list(42))

produces what you want?  At any rate, R shouldn't segfault so it looks 
like bug somewhere.
