Comment(by rl):

 The problem is that since we don't vectorise the standard library yet, the
 vectoriser chokes on any calls to standard library functions. The
 desugarer introduces such calls (mostly to patError) even when they aren't
 necessary so we rely on gentle simplification to remove them before
 vectorising. This is indeed quite fragile but is only a temporary measure
 until we can vectorise the libraries.

 I'll try to find out what exactly is happening there over the weekend.
