Bug #7687 for DBI: Attempt to free unreferenced scalar in FETCH

Subject:

Attempt to free unreferenced scalar in FETCH

A minimal test case which produces unusualy warnings under perl 5.8.x, linux, windows, and perhaps others: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= use DBI(); my $sponge = DBI->connect("dbi:Sponge:","",""); my $sth = $sponge->prepare('foo', { rows => [ [ 'bar' ] ], NAME => [ 'baz' ], } ); $sth->DBD::_::dr::FETCH("NAME_hash");

By the way, the use of Sponge is only to provide a minimal test case; this error is seen on production drivers (DBD::ADO for instance) as well. [guest - Fri Sep 17 20:21:09 2004]: Show quoted text

Why are you calling $sth->DBD::_::dr::FETCH ? Firstly that's an internal method for drivers and shouldn't be called directly. And secondly it's a driver handle method and you're calling it with a statement handle. There may be an issue here, but I can't given it any priority unless you can reproduce it with more "normal" code. Tim.
