This segfault occurs when using psqlodbc-07.03.0100 and DBI 1.35, with
postgresql 7.4beta4 and also 7.3.4. This is on i386 architecture with
Debian Linux.
In the log we have:
Oct 21 12:08:45 linda postgres[10923]: [2-1] LOG: connection received: host=127.0.0.1 port=42389
Oct 21 12:08:45 linda postgres[10923]: [3-1] LOG: connection authorized: user=olly database=bray
Oct 21 12:08:45 linda postgres[10923]: [4-1] LOG: unexpected EOF on client connection
I have not been able to trace the program because I haven't yet worked
out how to set breakpoints in a module loaded after the run command in
gdb.
$gdb perl
