Macsbug v6 and newer also has:
ATR -- begin trap recording
ATP -- type out on screen info about the last 2 dozen traps.

Most random death after 'n' minutes crashes are caused by unlocked handles.
test under heap scramble (HS) in Macsbug. Consider using the Check heap
before each trap command in MacsBug, and use the Mr. Bus Error INIT, available
on the developer's CDs, which will help you catch NIL pointer dereference
errors.  (It is amazing how much commerical software out there shows up
as buggy under Mr. Bus Error.)
