I can reproduce it on two systems

    GNU bash, version 2.05.0(1)-release (i686-pc-linux-gnu)          [SuSE
7.1]
    Copyright 2000 Free Software Foundation, Inc.

    GNU bash, version 2.05.0(1)-release (i586-pc-cygwin)
    Copyright 2000 Free Software Foundation, Inc.

Both built from ftp.gnu.org sources with "official" patches 1-4 applied.

Uwe
