On my Windows machine, Lilypond stops working at the "Preprocessing

Lilypond, but don't reckon it should.

Where does the cutoff seem to be?  i.e. try 200, 400, 600, 800...?

Also, as you certain that it *crashes*, or does it just take a
long time?  Try timing the code at 200, 400, 600, 800, etc -- look
for a pattern, and if you see a pattern, you might be able to
predict that (for example) it should take lilypond 5000 hours to
complete the example you gave it.

On 12.2.3 it will process 1150 repeats, but not 1200. On 12.13.35 1050 is OK, 1100 is not.

I've attached a graph of how both use working set memory - it does appear to be related to trying to allocate a total of more than about 450 megs. It's not a problem with physical memory being available - my PC has 6 Gig and it's nowhere hear using it all.
