Why, here?  Previously it was an undefined symbol defined
elsewhere (see below).  Why does it have to have a size *here*?
Why doesn't that affect the test?

Mmph, why not in expdyn1.s, where it's defined?

This whole section moved?  Is that right?  Hm, I don't set it to
writable anywhere in the input, so maybe moving it to the code
area (0... not 2...) is something that can be expected.  Still,
it subverts the original test which expected to get a (separate)
sequence of bytes in a new section, not .text.  Pretty please
fix, say in sec-7a.s.
