 Can you try the following patch to src/sbin/dump ?
 
 I think it is likely to apply fairly cleanly to any (moderately recent)
 source tree - but the sole change is to alter the type of the
 blockswritten variable from int to u_int64_t.
 
 A version of NetBSD old enough might be missing the "extern" in dump.h,
 and the variable declaration in main.c entirely, that's OK, just
 change the data type from int to u_int64_t  (it should be the same as the
 "tapesize" variable).
 
 If this works for you I'll commit the change to the tree, and request pullups.
