I think the above patch is correct.  Do you see a problem with it?

What it does do is expose other bugs in gas, in this case that
read.c:pseudo_set throws away the correct segment returned from expr()
and instead replaces it with expr_section.  Trouble is, looks like
using the correct segment there exposes yet more problems.
