[clean-list] compiler crash again

[Divianszky Peter]

I tried my previous crash project with the compiler downloaded this
week with cvs, but the result is the same "index out of range" during the
compilation.

I think this error could be fixed easily, because when I change the order
of lines in the dcl file, everything seems ok.

Please help me fixing the bug,
Peter
