Well optimization is done independently of creating and storing debug
information. To test without optimization I edit the file src/Makefile
at the line


CFLAGS = -g -O2 -fdiagnostics-color=auto   -I/usr/include/glib-2.0 ... 

to read

CFLAGS = -g -O0 -fdiagnostics-color=auto   -I/usr/include/glib-2.0 ... 

(It's quite extraordinary, but I've never noticed any performance change
when running like that! But debugging is much easier).

It'll take me a little while to work out what to do next (we *may* be
chasing some bug that is not actually in Denemo, but the fact that it
happens while exercising code that I have recently altered is highly
suspicious of some un-initialized pointer). Bear with me.
Meanwhile it might be worthwhile to generate another 

        make clean && make 2>&1 | tee make.log

to be sure that there are no warnings being ignored.
