This is fixed by commit 1baa215, which will be in Guile 2.0.12.

It turns out that when shrinking a bytevector, as happens before
‘get-bytevector-n’ returns, the pointer to the bytevector’s contents
would not be left pointing to the old bytevector.  When that old
bytevector was eventually reclaimed, anything could happen.

Thanks!
