The solution to make such cleanup may be GEMDOS vector VEC_CRITICALERR 
as described here:
http://cd.textfiles.com/ataricompendium/BOOK/HTML/CHAP2.HTM#gdvectors

Another solution could be to hook the 68000 exceptions vectors directly 
(bus error, adress error...). The MiNT function Psignal() with SIGBUS, 
etc. may work, or even the signal() function in the MiNTLib.

OS experts should tell us wich method is the good one.
