I believe this is fixed by the switch to Guile 3.0.4 in commit
a2991de0f44a5f4db71ddad67e914fe3344a4505 (June 2020), where ‘-O1’ uses
the new “baseline compiler”, which is much less memory-hungry.

<https://berlin.guixsd.org/search?query=guile3.0-guix+system%3Ai686-linux>
suggests it happens only occasionally.  I suspect it’s more likely when
doing ‘-j 96’ than when doing ‘-j 4’ because the former requires more
memory.
