Oops, I missed this in my first read. I'm definitely nit-picking here,
but this should probably be:

    if (chunk_offset % expected_alignment)

without the trailing "!= 0".

I don't have a strong preference here, since we are doing a comparison
of an arithmetic operation against an (un-)expected value. But I think
the CodingGuidelines would technically call this out of style...
