After double-checking, I've discovered that I've misunderstood the code, 
and the input section's size is not updated by the conversion process 
(the conversion appears to affect local data only), so the patch would 
be broken for compressed data.

This patch should solve my problem without creating a new one.

As for the testcase, after tweaking the pad amount, it only fails on 6 
of the targets Alan listed, for which I've added xfails. I presume 
they're doing some conversion on the input section size such that the 
data size *should* be the output size (valgrind shows no issues).

OK?
