Orion,

Have you looked at this recent bu report:
https://savannah.gnu.org/bugs/?49760 ?

Apparently Octave may not be using zlib precisely correctly.  There is a
patch on the bug report that follows the zlib example code more faithfully
and resolved the error for the reporter.  You might might try installing
the patch and see if it addresses your problem as well.
