    77This is essentially the same issue we faced with PARI in #22633, but applied to GAP.  In fact, GAP's code sets the default value of the `-s` flag to 0 on Cygwin, presumably for reasons related to this.  This might be possible to avoid, as was done in PARI, by instead allocating this memory with `mmap` and `MAP_NORESERVE`.
