I just noticed that my mail to the list of Feb 18 bounced. Sending again. I don't know yet what the problem was, perhaps it's to do with the new server on which the list is hosted. If someone else sent mails to the list recently and got no replies, you might want to check in the archives if it arrived ...

I cannot reproduce a problem with your code fragment (in particular, the declaration of the arrays etc. might be relevant).
Could you please send a complete (minimal) program that exhibits the problem -- preferably in a way that we can use it for our test suite? (If you don't have access to another email account, you can use the upload form on the GPC web site and state in the comment field whether we may distribute the code.)
