Description
My system crashed and for some unknown reason the core was incomplete. Trying to decompress it with savecore -vf resulted in a floating point exception because 0 pages were saved, and savecore then does this:
(void) printf("%ld (%ld%%) zero pages were not written\n",
(pgcnt_t)zpages, (pgcnt_t)zpages * 100 /
dumphdr.dump_npages);
