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’.

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)))
