A lisp package should not be able to crash Emacs.  You can try to set these in 
your environment before starting Emacs from the command line:

export NSZombieEnabled=YES
export MallocGuardEdges=1
export MallocScribble=1
export MallocErrorAbort=1
export MallocCorruptionAbort=1
export MallocCheckHeapStart=1000

Emacs will run very slowly, but hopefully it will print something useful if it 
is a memory issue.
