The problem is a stack overflow in the Mercury compiler.  Everything is
fine in the current rotd builds and I don't think we've adjusted the
cstack reserve size we set in compiler/Mmakefile, so presuambly one of
the changes between 14.01 and now has fixed this.

I'll try to isolate what has changed, but unless it's relatively small I
don't think we'll be able to merge into on the release branch without a
lot of fuss.  The best workaround for users encountering this issue at
the moment is to use a recent rotd build.

Cheers,
Julien.
