I posted this mail to the HELP list earlier. Meanwhile we are quite shure that there must be a bug. Not nessecarily in R. But maybe we can get some hints how to track the problem using R. Currently we are trying something with the ATLAS lib according to Bug Report 7718 on this Repository.

Now my problem again:

We have a data server with some amounts of data which we try to analyze using R. Now having some MySQL databases with MySQL Ver 12.22 Distrib 4.0.24 and R 2.1.0 compiled from sources on this machine:

Fujitsu Siemens CELSIUS V810
4 GB RAM
Dual AMD Opteron Processor 246
Harddisk via SAN.

(see user details:)

sysname                         "Linux" <- gentoo linux
release		"2.6.11-hardened-r13"                               version "#1 SMP Fri
May 27 15:25:55 CEST 2005"                               machine 				"x86_64" 

Editor: Emacs with ESS 5.2.3

While I can connect R to the database (RMySQL/DBI) and retrieve basic information (e.g. SHOW TABLE, DESCRIBE) it is not possible to send SQL Queries. The moment I try to do: res <- dbSendQuery(con, "select * from table") or any other SELECT statement R terminates and I receive a Segmentation Fault.

Is anyone out there having similar problems in this environment. Any hints welcome.
