System: 32 bit x86 Fedora 16
(use-modules (rnrs bytevectors))
(define not-32-bit (expt 2 32))
(define bv (make-bytevector 4))
(bytevector-u32-set! bv 0 not-32-bit (endianness big))
(pk bv)
Running this gives me a core dump. It happens for a wide range of values
that don't fit in 32 bits.
After some talk on #guile, Mark and I believe it comes down to the range
check in INTEGER_ACCESSOR_PROLOGUE in bytevectors.c
