I'm going to close this report, or should it be reassigned to odbc-postgresql, trying to fix it by using gcc-3.4? I've now tested the above. Using the original Sarge environment, but with gcc-3.4 instead of gcc-3.3, the same segfault behaviour arises.as originally described. My conclusion from that is that the segfault arises because of a bug in gcc which happens to have been fixed in gcc-4.0; although there's an outside chance that some of difference between the Sarge and Etch environments may be to blame, but that's unlikely IMO.

Is it possible to make a standalone test case? I've just tested this out. I only have a single, production amd64 system and so I did this using a chroot. I bootstrapped Sarge into the chroot, and then added the Etch sources to /etc/apt/sources.list in order to enable me to install gcc 4.0. First rebuild resulted in lots of unhappiness during dpkg-buildpackage including Unknown gcc system type x86_64-linux-gnu at which point I realised that gcc 4.0 in Etch uses libc6 2.3.5, which is newer than Sarge. So, I restarted and just made an Etch chroot instead :-) Building the odbc-postgresl package in a minimal Etch environment using gcc 4.0 resulted in a working package as the end product, but there were a very large number of warngings during the compilation: info.c: In function 'PGAPI_Tables': info.c:1364: warning: pointer targets in passing argument 4 of 'schema_strcat1' differ in signedness info.c:1364: warning: pointer targets in passing argument 6 of 'schema_strcat1' differ in signedness info.c:1366: warning: pointer targets in passing argument 4 of 'my_strcat1' differ in signedness info.c:1367: warning: pointer targets in passing argument 4 of 'my_strcat1' differ in signedness... (lots of the same, I will post in its entirety if required, but I suspect the warnings are due to the strictness of gcc 4.0?) Given that there were lots of warnings but no actual errors, I installed this package into the Etch chroot and there was no segfault after running the previously-described 'isql' tests using this version. However, this working version of the package cannot be used in Sarge, because of the libc6 dependency: Unpacking replacement odbc-postgresql ... dpkg: dependency problems prevent configuration of odbc-postgresql: odbc-postgresql depends on libc6 (= 2.3.5-1); however: Version of libc6 on system is 2.3.2.ds1-22. dpkg: error processing odbc-postgresql (--install): dependency problems - leaving unconfigured Errors were encountered while processing: odbc-postgresql The bug remains in the Sarge version of course, but that would appear to be a compiler bug in gcc 3.3.

Bug#318865: odbc-postgresql: Segfault when running ODBC describe, amd64 client
Package: odbc-postgresql
Version: 1:07.03.0200-5
Severity: normal
Apparently specific to amd64 installation only, an ODBC client request
for table/view structure ('describe table') results in a segfault.
Example isql session:
$ isql DSNname myuser mypass
+---+
| Connected!|
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---+
SQL help
(output returns list of all tables and views, as expected)
SQL help mytable
Segmentation fault
I note that issuing a direct SQL query, with prior knowledge of the
column names etc., is successful:
$ isql DSNname myuser mypass
+---+
| Connected!|
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---+
SQL select * from mytable;
(table output returned as expected)
Additional information:
- Above behaviour is reproducible and identical for connections to two
different postgresql server installations (both on other boxes), one
is postgresql 7.2.1-2woody8 (current Woody release) and the other is a
slightly out-of-date Sarge running postgresql version 7.4.6-5;
- On a similar system which is i686 rather than amd64, the segfaults do
not occur - 'help mytable' returns the expected table structure, so
this bug appears at face value to be specific to the amd64 version of
odbc-postgresql;
