This should have been addressed in a commit ~6 months ago:
https://charm.cs.illinois.edu/gerrit/#/c/696/4/src/util/charmrun-src/charmrun.C
That's part of the just announced 6.7.0 release. What version are you running there? It's not apparent from the log you linked.

Motivation: I am trying to enable Charm++ and AMPI in Travis CI for the Parallel Research Kernels.

Problem: See below.  I cannot launch Charm++ programs with charmrun because ssh fails.  Because this is Travis CI, it is not interactive, and whatever needs to be done to fix the otherwise trivial issue with localhost authentication needs to be something that can be completely automated.

Is there a way to tell charmrun to ignore the localhost issue?  If not, can one be added?  I'd like to avoid making a change downstream because then I'll have to verify and possibly redo it for future releases of Charm++ if charmrun changes.  And I don't want to be mucking around with SSH settings in Travis CI instances.
