[Message part 1 (text/plain, inline)]
Hello schemers,

the bytevector->uint-list procedure from (rnrs) can crash Guile through
a division by zero:

scheme@(guile-user)> (import (rnrs))
scheme@(guile-user)> (bytevector->uint-list #vu8(0) 'x 0)
Floating point exception

The same happens with bytevector->sint-list. These procedures also do
not check that the length of the bytevector is divisible by the size.

Tested with GNU Guile 2.0.9.71-8d5d04.

Regards,
