I am also able to reproduce the issue on amd64 (although mostly with
SIGTRAP, only rarely SIGSEGV), when not using a separate $HOME directory
like done in debian/run-tests.sh.

A strace shows a lot of stat on files, and I wonder if it's not just a
timing issue: scanning all those files or a slow architecture are
triggering the issue. Using that way to reproduce the issue on amd64, I
can confirm that the issue is not reproducible with 4.10.1+ds-2 and is
first reproducible with 4.10.3+ds-1.

Also note that after many tries, I have been able to get a successful
build on riscv64 that I uploaded into the archive. We'll see if it can
be rebuilt on the buildds once all packages of the loop are available,
which might take a few days.
