Yes, we know about this bug, hence the error message.  Unfortunately, it is
tricky to fix, because both the runtime interpreter and the garbage collector
use the highest-bit of a heap address for some internal purposes.  However,
we have a student who has sketched out some potential solutions to the
problem, and are hopeful that it can be fixed in the next month or two.
