https://github.com/Macaulay2/M2/issues/500says there it's the Boehm GC beingconfigured for small memory by default. They say setting the environment variable GC_INITIAL_HEAP_SIZE (tolike "50G") helps. Not sure why. Also, there's an environment variable GC_MAXIMUM_HEAP_SIZE.

I believe this is fixed by the switch to Guile 3.0.4 in commita2991de0f44a5f4db71ddad67e914fe3344a4505 (June 2020), where ‘-O1’ usesthe new “baseline compiler”, which is much less memory-hungry. Ludo’.
