SIGSEV in destructor

I'm observing SIGSEVs in compiled code that occurs within
a -destructor method. The destructor looks at some member
variable (and issues a warning depending on the value).
When I comment this line out (looking at the member variable)
the SIGSEV does not occurr.

My hypothesis is that the error occurs because
lisp_c:wipe_out_temps() deletes the member variable before
the object itself, hence, before calling -destructor.

I'd appreciate any advice on fixing this or on confirming
the cause.

Thanks,
Ralf
