Hi.
Great, it's now much more readable!

I guess problem is that all numbers are zeros. Easiest what you can
do is to run normal GCC with -fmem-report and add '-wrapper gdb,--args'.
That will open GCC in debugger, that you can place a breapoint and you'll
see a backtrace.

The output looks good for trees.
