R help - Aug 2006 - Attempt to access unmapped memory

Hi,

I am usiing R 2.3.1 under Linux kernel 2.6.11 with libreadline/libhistory 5.1. 
Bothe R and readline were compiled without quircks with gcc 3.3.3 and g77.

Every time I try to edit command line by using del key the following error 
happens:

------------8><--------------
> ipacks <- instaleld.packages()
 *** caught segfault ***
address (nil), cause 'memory not mapped'

Possible actions:
1: abort (with core dump)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: Segmentation fault
------------8><--------------

As I have readline 4.3 installed too, I adjusted the symlinks to point to 5.1. 
No problem with bash. This setup works fine in another machine with same OS 
and versions.

Any clues?

Thanks in advance.

That is known to be buggy.  Either patch it or downdate to 5.0.
