'u8-list->bytevector' uses the SCM_VALIDATE_LIST_COPYLEN macro to validate the list and simultaneously compute its length. That macro implicitly assumes that its third operand will be a variable of type 'long', because the result of 'scm_ilength' is assigned to it, and 'scm_ilength' returns a 'long'. After storing the result to the variable, it checks to see if the result is negative, which would indicate that the operand wasn't a proper list. The bytevector operations that convert integer lists to bytevectors pass a variable of type 'size_t' to SCM_VALIDATE_LIST_COPYLEN. Since 'size_t' is unsigned, the -1 result from 'scm_ilength' was interpreted as ULONG_MAX instead. Thanks for the report.
