I just tried running smokegen in gdb. I looked at the command used to run it
in the qtcore/CMakeFiles/smokeqtcore.dir/build.make makefile, copied the
command line and gave it to gdb. I think this should not change anything with
respect to running it from the makefile itself. However, here's the result from gdb:

75              return _q_value != value;
