Guile segfaults when a vector is created with size >= 2^16 = 65535.
Observe:

scheme@(guile-user)> (define v1 (make-vector 65534))
scheme@(guile-user)> (define v2 (make-vector 65535))
Segmentation fault

It also fails for greater sizes.

Curiously enough, this works:
scheme@(guile-user)> (define v2 (list->vector (iota 65535)))

Hi Tobias,

To my surprise, the bug did exist in HEAD (I had tested only 2.0.)
It is fixed in c336514976ed3f2b2b20c56149ede7f5ec549c52.

But really, HEAD is for the brave.  It currently aborts in the middle of
./check-guile for me.  ;-)

Thanks,
Ludo’.
