Subject: core dump under mod_perl
DBD::Pg 1.31, perl 5.8.2, mod_perl 1.29, apache 1.3.29 (with mod_ssl), FreeBSD 4.9, Postgres 7.4 libraries talking to a 7.2.4 server. I upgraded from DBD::Pg 1.22 to 1.31, and now the httpd dumps core when started. My httpd startup queries the database for some configuration information for the application, and this is where it croaks according to gdb: #0 0x285b5f4b in dbd_st_fetch () from /usr/local/lib/perl5/site_perl/5.8.2/mach/auto/DBD/Pg/Pg.so For now I'm backing to DBD::Pg 1.22 which has been stable. Standalone apps still work fine with DBD::Pg 1.31, however. I'll attempt to reproduce the environment and error on a development box with debugging on, and provide some more info.

There was a tiny problem with unknown field types causing DBD::Pg to segfault. The attached patch should fix it. This is also fixed in CVS HEAD. Rudy
