[R] Random termination of R with RODBC and PostgreSQL 8.2.6

Dear list,

I get random terminations of R when using RODBC with a remote PostgreSQL 8.2.6
database under Ubuntu Linux 7.10 32bit client.

The exact messages can be seen below. It seems that there is some memory
corruption going on. But it seems random to me and can neither be related to
addPK=T/F or fast=T/F. It can happend for all possible combinations. Besides I
do not really understand what these messages mean.

Any idea to what it is related exactly?

Thanks in advance,
Ulrich Leopold
