xpectedly

It could be a non-deterministic bug in =E2=80=98substitute-binary=E2=80=99.

Could you try running this:

  ulimit -c unlimited
  while make check TESTS=3Dtests/guix-build.sh ; do : ; done

If you manage to reproduce it this way, can you check if there are more
details in the log, or a core dump?  If not, could you add debugging
statements in substitute-binary.scm to see how far it goes (that needs
to print to (current-error-port), not to (current-output-port))?

TIA,
Ludo=E2=80=99.
