The following sniplet segfault when trace is activated:
#!/usr/bin/perl
use DBI;
my $dbh = DBI->connect("DBI:Pg:dbname=olacacea;host=localhost;port=5432",
guillaume) or die("Can't connect: $DBI::errstr");
$dbh->trace(1);
without trace:
[guillaume@baader db]$ ./testcase
Database handle destroyed without explicit disconnect.
with trace:
[guillaume@baader db]$ ./testcase
DBI::db=HASH(0x81c6ef4) trace level set to 1 in DBI 1.30-ithread
Note: perl is running without the recommended perl -w option
Database handle destroyed without explicit disconnect.
Segmentation fault
I suspect this is a multithread problem...
I am running Linux Mandrake, and here are relevant informations:
