Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

Hi James,

Could you specifically confirm that this crash is still observed with
6.7.0 and 6.7.1? I feel like this is somewhat familiar, but would have
to do more digging than the brief search I've done to figure out
where/why/when.
