No strong opinions here -- it's certainly a latent bug, but triggering
it is relatively difficult with 4.0.
Basically we need to evaluate the risk/reward. We can fix this with the
exact same patch that we're using in mainline right now which hasn't
caused us any problems yet. That patch is also very similar to what was
done for one or more of the 3.x release branches. I consider the patch
relatively safe.
What's the reward -- a latent code generation bug is fixed.
So is the reward worth the small risk the patch poses?
[ Note that if we had a bug report with 4.0 which was traceable to
this problem, then I'd clearly land on the side of installing the
patch. ]
