Nice.

Is there a corresponding opposite-direction macro that should be
added?

This suggests a broken makefile, though most makefiles are broken in
the same regard... Because the program crashed while writing a target,
that target, probably corrupted, exists with a valid timestamp and
causes make to think it doesn't need to be generated the next time
around. Really, any command in make should move the successfully-built
file into place _atomically_ (e.g. first writing to a temp file then
moving it) so this can't happen.

Anyway, to get back on-topic, I suspect the generated file was
incomplete/corrupt and this might be causing problems later down the
line.
