    MM> well, try this (without package polynom):

    >> parse(text="1 + x*(100 + x*(4950 + x*(161700 + x*(3921225 

and then I had the full length 2404 string which---I had
"known in advance" (Murphy's law)--- has been thrown up
before it got back to R-devel, actually by my mailer already.

Now this should be easier to pass through:

 tt <- tempfile() 
 download.file("ftp://ftp.stat.math.ethz.ch/U/maechler/R/longpoly.rda", tt)
 zh # look at the long "polygon string"

 parse(text=zh) ## seg.fault
