Can you be more specific about moves you have made? I cannot reproduce.
You are correct. Now I works.
I compiled the latest version and it died 5 times, when I tried it with different patterns. Always the same error message.
How ever I retried the file I sent you and now it didn't fail. Now the other patters work as well.
It is very weird. I always try recheck everything to avoid my own mistakes.

Don't worry, sometime this happens. Anyway, thank you for bug reports.
