Nice one.
However do you come up with such code?
(This is meant as a compliment)

It is part of code for handling groups, starting from a pascal translation of http://www.ccl.net/cca/software/MATLAB/Irreducible_representatives

Cryptic looking code and the use of MC := Copy(MC) is a little strange and senseless,

But , I can say this, it compiles fine with 3.0.4. Not sure about 3.2.x

Note the bug report specifically mentions trunk; it compiled OK until recently.

This is a stripped down example; the original copied to a different place.

yes. I was just making comments about the twisted looking code and yes I does compile with other versions, can't say if it executes properly, that is another mystery.
