That's odd, since adding __attribute__ ((cold)) should affect only performance. 
If it causes a core dump, that suggests that there is a bug either somewhere 
else in Emacs (which __attribute__ ((cold)) happens to tickle) or in the 
compiler. Can you reproduce the problem when compiling with '-g3 -O0 -gdwarf-4' 
and get a backtrace, as suggested in etc/DEBUG?
