It's not. (And even if it were, dbi-dev isn't meant for reporting bugs.
The dbi-users list is fine for that.)

And since the DBD::Oracle code was the same, that implies it's not a
DBD::Oracle bug. Does seem very odd though.
A level 5 trace will show you what Oracle is returning for each field of
each row. If that shows the bad data then it's almost certainly an
Oracle bug. If it doesn't (ie it shows different values being returned
than what eventually gets returned by selectall_arrayref) then it's a
DBD::Oracle or DBI bug - but at the moment I doubt that.
