This appears to be a real bug (see ChangeLog.8:7259; the macro can return
NULL realistically), and there are several similar lines in xdisp.c:
19988, 20088, 20430, and the reported 20517 in revision 1.1096.
It might be the case that those lines cannot be executed without the font
being known valid from previous branches (including returns), but the last
one -- the one that was actually reported -- looks pretty "bare" in that
sense. I don't know nearly enough about fonts to say how to fix it,
though.
