Comment (by hvr):

 Replying to [comment:27 svenpanne]:

 Sven, I'm not sure you're seeing the full picture here. The (questionable)
 popularity argument is completely off-topic and irrelevant to the issue at
 hand. Releasing a quickfixed GHC 8.4.3 would still undermine the whole
 idea of Stack's "LTS" snapshot releases and its (imperfect)
 "reproducability" concept, as this problem isn't limited to GHC 8.4.* but
 rather extends back to GHC 8.2.1.  As such I see no reason for yet another
 rushed quickfix release of GHC, for something that *must* be fixed on
 Stack's end anyway in order to be effective. And it would be quite
 laughable if Stack wasn't in a better position to release a quick fix than
 for GHC HQ to make a full compiler release (which I have to emphasize
 wouldn't be sufficient anyway for users that are forced to use Stack and
 their GHC 8.[24].[12] snapshots to keep working with the affected GCC
 versions)... ;-)
