OK, you might get a different backtrace now using a build without  
-fomit-frame-pointer. If so please post it back to the list - this  
could be why there were ?? entries.

For debug, the flag is -g, but the Geany build system normally enables  
this already. Also for debugging it's best not to optimize higher than  
-O2.

Thanks, memcheck is just a heavier version of addrcheck.

Unfortunately Valgrind didn't reveal anything in Geany directly causing  
a problem, so it could be some incompatibility or a bug in GTK  
2.10.0/GLib 2.12.1.
