Details:

Hashing using ones own hash functions does not survive a hash resize.

If the assoc function returns #t, a segfault or bus error results.

A patch to the test suite demonstrating these and testing a few other things
is attached.

As an enhancement request, it would be nice for the common case to be able to
pass a hash-function argument and assoc to make-hash-table or to have a
(make-hashx-table hash assoc [size]), and in either case to remember the hash
function so that resize works correctly.

Thanks,
Grem
