That segfault is from readline, not R itself.

and where did you get readline from? (Is this some Linux distribution?)

Thanks for the detail, which enables me to guess at how to solve this....
Suggestions:
(1) configure with --without-readline and see if that works (it
should, since make check does). You `just' lose the command-line history.
(2) Compile the current readline sources yourself and use that, building
from scratch. In so far as your spec looks like RH6.2 with gcc-2.95.2 added
(from memory), that has a good chance to work as it did for me. It might
matter that readline is compiled with the same compiler as R. (I know it
should not, but RH6.2 seems to have some problems making dynamic libraries
with the supplied egcs.)
