Hi Busybox List,

Output of Busybox v1.28.1 built in Buildroot:

dd if=/dev/zero bs=1 count=15 2>/dev/null |hexdump -C
*

Output of bsdmainutils 11.1.2 (Debian):

dd if=/dev/zero bs=1 count=15 2>/dev/null |hexdump -C
00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00     |...............|
0000000f

With 'count=16' both implementations produce the same output.

I'll try to look into this later.
