Comment (by Phyx-):

 Yeah, so what confuses me too is that it's also in the rts's package
 config. I think the linker log with - Dl would shine a light on it. A dump
 of one that fails and one that doesn't should show what changed.

 It should indeed be quite deterministic. What it could be is that it's not
 print itself causing the inclusion but that there is another symbol in
 that object file that is sometimes required and other times not.

 For instance one invocation may be lasting longer than the other,
 different order in GC? Or in one case a finalizer being called but not the
 other.

 But the log would show what demanded the object file be loaded.
