Ok, I see.

The package works only by luck, the warning does indicate that something
wrong is happening. I do think that in the case of hwloc it could very
well crash, because structures have changed between hwloc1 and hwloc2.

Personally I almost always leave the stderr check, because most often
they are a sign of something wrong happening, and we want to fix it
somewhere, even if it is harmless for the test at case.

Perhaps what we are lacking here is a button for the maintainer of the
migrating package and the maintainer of the failing package to be able
to say "never mind, this is fine", and/or another to say "please retry
this with all to-be-migrated packages". That could cover most of the
cases, without the debian-release team having to delve into them.
