Hmm.. I didn't do any debugging on the second bug reported, but it seems to me
that once a section was marked dirty, outputting to a new elf causes it to
only consider data explicitly added to the lib internal memory representation
of the elf.
It _did_ write out the data I added via elf_newdata(), and entered the
appropriate offsets into the header file, but completely omitted copying of the

Still, I'm a bit baffled that a bug like this could exist for so long in .. well
I guess these are kind of core developer utils, right?
Or maybe I'm doing some really sick stuff noone else dreamt up yet ;)
