Hello,
   thank you for your bug report.

A side note: the grep bug-address has changed to address@hidden,
so please move the discussion (if any) there.  (Reply-To field set.)

in short, the test suite is in a bad shape.
But the grep program itself should work correctly.

In detail:

Correct result would be exit code 2, but the test suite requires 1.

The problem is that the regex code distributed with grep has a bug
which matches the bug in the test.  So when you use the included regex,
the bug is hidden.

On GNU/Linux, you use the system regex, which works correctly, and the
bug in the test demonstrates itself.

This regex is extremelly slow when run with the system regex on GNU/Linux
systems.

Both problems are addressed in the CVS on savannah.gnu.org.
