Follow-up Comment #5:

confirming the issue occurs on 9.1.0 and not on 8.4.0.  legend in 8.4.0 is
calling `__go_patch__` the same way in both versions, so the issue does seem
related to changes in graphics.cc.  testing different revisions, that error
started with 
https://hg.savannah.gnu.org/hgweb/octave/rev/c4500208f280

that push was intended to prevent an octave crash from inconsistent user input
to patch.  might take a bit more digging to see why legend's input to
`__go_patch__` is breaking things.  that' buried in graphics.cc, though, so a
bit tougher to step through and probe than the other m-code.
