Simon -- I can't reproduce it for the list because the window it's running in 
always hangs and R freezes. I tried. But it basically looks like

dump("my.file",file="myfileR")
source("myfileR")
HANG..... (yellow colored ball)

I will go with your suggestions below and report back if need be.   Thanks for 
the help.

I checked the archives since the release of R 3.0.0 and didn't see anything on 
this.

Trying to import data previously exported with dump(), source() hangs and I 
have to force quit R.  This happens with data objects
as small as 5 kb.

Do you have a reproducible example?


Has anyone encountered this and found a workaround?  Is there now a preferred 
method to export R objects?


The preferred method has always been to use serialization (save/load or 
saveRDS/readRDS).

Cheers,
