I've already checked. I don't know the reason why the codes on both sides are different.

The origin code:
fprintf(stderr,"Can not write all of dump data bytes=%zd len=%zd\n",

The CI code:
fprintf(stderr, "Can not write all of dump data bytes=%ld len=%ld\n",

CI run is on top of the 'mrvl' tree (DPDK git baseline:
Repo:dpdk-next-net-mrvl), and above part may be fixed while pulling to the
'next-net'.

Anyway the latest code looks good (for above change), also the error is
unrelated to your patch. So a false positive for this patch.
