=head2 Changes in DBI 1.57 (svn rev 9639), 13th June 2007

Fixed t/86gofer_fail tests to be less likely to fail falsely.

t/86gofer_fail.t now fails with my build of bleadperl (patchlevel 31376)
with VC++ 6.0 on Win32 (perl -V below). This script was passing OK in
DBI-1.56 with the same perl.

C:\Temp\DBI-1.57>perl -Mblib t\86gofer_fail.t
ok 21 - negative percentage should fail non-randomly
Testing random delay
ok 22
Unexpected failure: DBD::Gofer::db do failed: Assertion !((sv)->sv_flags & 0x00010000) failed: file "..\pad.c", line 1505 at
C:\Temp\DBI-1.57\blib\lib/DBI/Gofer/Execute.pm line 624. at t\86gofer_fail.t line 129.

Execute.pm line 624 is returning a closure, but it doesn't seem
particularly magical.

Not sure when I'll be able to dig deeper. CC'd to perl5-porters in the
hope they can help narrow it down.
