BASH PATCH REPORT
=================
Bash-Release: 4.2
Patch-ID: bash42-041
Bug-Reported-by: Andrey Borzenkov <arvidjaar@gmail.com>
Bug-Reference-ID: <20121202205200.2134478e@opensuse.site>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2012-12/msg00008.html
Bug-Description:
Process substitution incorrectly inherited a flag that inhibited using the
(local) temporary environment for variable lookups if it was providing
the filename to a redirection. The intent the flag is to enforce the
Posix command expansion ordering rules.
Patch (apply with `patch -p0'):
