My reader script shouldn't do anything that increases the size of the header
before I write it.  I can double-check my reader to see if it's doing anything
to increase the header size though.  The odd thing is that it successfully
saves the header for some messages but fails this way for others.

I've updated the debug dump to expand field_list.
This is the original header before my reader modifies it:

And this is the header after it applies the MSG_READ attribute:
