Summary0000111: Wording descriptions of phrase arguments with ``that is'' leads to an ICE
DescriptionIn the source, rather than just ``four'' I've written ``a number that is four.'' The compiler reacts by giving this message:

An internal error has occurred: made null as atomic Types__KOVs__base_object. The current sentence is 'To consider (X - a number that is 4)' ; the error was detected at line 129 of "Chapter 15/Kinds of Value.w". This should never happen, and I am now halting in abject failure.
What has happened here is that one of the checks Inform carries out internally, to see if it is working properly, has failed. There must be a bug in this copy of Inform. It may be worth checking whether you have the current, up-to-date version. If so, please report this problem via

 As for fixing your source text to avoid this bug, the last thing you changed is probably the cause, if there is a simple cause. Your source text might in fact be wrong, and the problem might be occurring because Inform has failed to find a good way to say so. But even if your source text looks correct, there are probably rephrasings which would achieve the same effect.
Minimal Source Text To Reproduce
There is a room.
To consider (X - a number that is four): say "Four."

An obscure inability to determine the kind of the free variable in "number which is 4". Fixed.
