Moving the check for $read == 0 was quite appropriate. Admittedly, $skip was not optimally named. (I'd prefer $in_bad_record. It was called $skip because I initially discarded the bad stuff. I didn't notice you wanted to keep it.) However, your fix of the bug in read wasn't optimal.

Me: 

   my $read = read($fh_in, $buf, $blk_size, length($ofs));

You: 

   my $read = read($fh_in, $newbuf, $blk_size);
   ...
   $buf .= $newbuf;

What it should be: 
   my $read = read($fh_in, $buf, $blk_size, length($buf));
