I've had similar problems with binary_archive. The archive is saved w/out
error, but crashes when reading it back in. When I've compared binary to
text archives, I see there is some header information missing from the
binary_archive. I was going to edit in the binary equivalent of the text
header info and see if the binary is then loadable. Alas, the MS hex editor
doesn't allow entry of non ascii bytes, and I got distracted by other
issues.
