| Subject: | bug in dbd_db_pg_notifies - sigfault in Perl_pp_leavetry |
OS: Linux 2.6.8-2-686 i686 GNU/Linux
perl: perl, v5.8.4 built for i386-linux-thread-multi
DBD::Pg: 1.43
DBI: 1.48
dbd_db_pg_notifies on error of PQconsumeInput returns int 0 instead of SV*
&sv_undef. This causes sigfault if used in eval{}
sample sode:
my $dbh = DBI->connect("dbi:Pg:dbname=test", "test", "test", {RaiseError=>1} );
while(1) {
eval {
$dbh->func('pg_notifies');
# here may (or may not) be other code:
# $dbh->do("select 1");
};
sleep(1);
}
now connection closed (postgres restarted) and we have coredump
correction patch attached
