On closer inspection, this is caused by OOM, with Guile peaking at 2.8G
resident (!) at that point, more than on x86_64.
I’m quite sure this is because the compiler resorts to bignums more than
on x86_64 (fixnums are smaller), thereby consuming more heap.
Splitting creates-io.scm into two files might work as a temporary
workaround since the compiler creates a number of labels (integers)
roughly proportional to the number of lines in the file:
