G'day,
Found a core dump on continuum. Desire a peer review of analysis.
So far my diagnosis is "an RCD was being decoded for transmission to
slot R0 (arizzi) from a slot (Xc) which was now in login, with a p_team
of 15 (ALLTEAM, main.c:239), causing the APPEND_CAP macro to (probably)
wander off."
But if this is the case, there are plenty of other instances in the
function where p_team or other data is used that may well have gone away
by the time we execute.
Here's the relevant portions of the core dump ...
