    11 Bug-Description:

    12 

    13 Process substitution incorrectly inherited a flag that inhibited using the

    14 (local) temporary environment for variable lookups if it was providing

    15 the filename to a redirection.  The intent the flag is to enforce the

    16 Posix command expansion ordering rules.
