Is the Maxima version with 1.0.2 same?

Does the length of the hibernation matter?

What happens if he sets *debugger-hook* to NIL before
hibernation? (Hopefully he'll get a backtrace that will
enlighten us.)

We start investigating problem in depth and
discovered the source of troubles. It is
neither sbcl (any version) nor Maxima but
some undeleted remnants of old builds.

I'm sorry for disturbance!
