R help - Jul 2004 - Seg Fault on R 1.8.1 under linux

This may be known, but if it is not, maybe it is helpful.
   h<- 1:1000;  save(h, file=pipe(">see"));
causes a Segmentation fault on my system.  The more sensible save(h, 
file=pipe("cat >see")) hangs.  I obviously have everything wrong
here,
my point is only about suggesting a better error trapping somewhere.

regards, /iaw

Yes, save does not check if the connection is

a) open for
b) binary
c) writes.

Three missing checks: file = pipe("cat >see", "wb") has a
chance of
working.
