Thankyou very much for posting that... Just solved my problem too. ++

Update: more info: exact same problem description, using ActivePerl under windows:

This is perl, v5.10.0 built for MSWin32-x86-multi-thread
(with 5 registered patches, see perl -V for more detail)

...

Binary build 1004 [287188] provided by ActiveState http://www.ActiveSt

... and Parse::RecDescent 1.94 (upgrading to 1.96 fixes the problem)

Update: upgrade to 1.96, not 1.60 :)
