Some things just take a long time to run diffoscope, and
tests.reproducible-builds.org only lets diffoscope run for 150m and then
kills it to avoid very large unreproducible packages from eating all the
resources.

Options would be to run diffoscope on two builds of halide locally. The
tool reprotest does this and runs diffoscope by default if it is
installed.

There is also beta.tests.reproducible-builds.org which may not have a
diffoscope timeout, so you might be able to find diffoscope output for
halide there.

There may be improvements that could make diffoscope run faster and
avoid the timeout, though I'm not sure this is a fundamental problem of
diffoscope.

I'll see if I can find you some diffoscope output for halide by running
it on a fairly powerful machine I have access to...
