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.
Thoughts?
