Summary0000159: liveness.m: Unexpected: branches of switch disagree on liveness
DescriptionFrom mercury-bugs

----------------

Dear all,
                                                                                                                                                                                                                 
having bought a new notebook (the previous one was from 2003), I've also jump-updated everything to the state of the art. The joy of recompiling old things has just
begun and here are the first fruits:
                                                                                                                                                                                                                 
rotd-2010-07-19 fails to compile the attached file (could be surely minimized yet a bit) with the following error:

Could you have a look at it? Disabling memoization solves it, but memoization alone is naturally fine. I guess it's the variable L where only the type and the value
is needed.
                                                                                                                                                                                                                 
Cheers and warm greetings to everybody!
