I think that the tarball is probably a few years old; the test suite
in CVS contains a lot more tests (and generates a lot more failures.)

It looks like it's actually failing on whatever follows MAKE-ARRAY.27;
the test name is generally only printed after successful completion.

I'm pretty sure that this was removed from the test suite a year or
two ago. Quick quiz: is (1+ 999999999999) EQ to 1000000000000 ?
c) that depends entirely on how an implementation represents FIXNUMs
and on whether or not 1000000000000 is a FIXNUM.
Since (c) is the correct answer, the test is bogus.

There are several differences of opinion on what (if anything) the
UPGRADED-ARRAY-ELEMENT-TYPE of NIL is. This is controversial enough
that newer versions of the GCL test suite have a switch which causes
tests which depend on a particular interpretation of that to be
