I suggest gzip + put it somewhere.

This is from the reproducible-builds log:

------------------------------------------------------------------------
make[1]: Entering directory '/build/reproducible-path/graph-tool-2.97+ds'
sh debian/show-mem-swap-nproc
===========================
MemAvailable:    1636328 kB
SwapFree:        7291176 kB
nproc: 12
===========================
dh_auto_build --max-parallel=1
cd _BUILD && make -j1
------------------------------------------------------------------------

I would say that trying to build a package like this with only 1.6 GB of RAM
is not realistic at all, so I would not consider this (the failed build
in reproducible-builds) to be a "real failure", and not enough evidence
to make the bug RC.

Is the build failure you got on arm64 similar to that, or it's really
different? Can you quote the part of the build log where available
memory and swap are shown?

Thanks.
