 This had no effect.

Oh, of course, it's that NDEBUG flag.  Sorry.  Try
abort();

 Is it possible to run rg from the RGbuild directory, without first
installing it?
How would I debug it using kdbg?
Compiling it with scons debug=full, setting the breakpoint in
MappedStudio.cpp and starting it through kdb didn't seem to work / be
enough.

Now I have used this, so that rg didn't stop after being started:
    tti += 1;
    if (tti == 3 ){
        abort();
    }

...and got this output when opening the file:
