I see now that the change which is said to cause the issue was committed on 2019-10-17 while 1.0.29 was released on 2020-02-02. So yes, it's probably a mistake in the issue description.
I tried to apply the change proposed in the upstream issue, but it does not compile: SCAN_FLAG_DISABLE_GAMMA not declared. Can you please let us know exactly how you applied it. Did you possibly compile without warnings?
