With just the following, we successfully compile your file. It takes about 25 minutes and memory use tops out around 40GB. Which still seems insane for a 1.6GB input file consisting primarily of data for a static array, but that's a different problem. At this point we usually have a PR to go with all stage4 changes. But a meaningful PR is difficult to create, since the attachment would be too large. Perhaps a generator could be created, but since it wouldn't go in the testsuite it seems like a waste of time.
