Unfortunately it wasn't, I personally tested Qt4 with tree-vectorize, it worked flawlessly, while graphite flags made it unstable. In that case there is no doubt that graphite triggered the instability.
Your test has been very useful though, letting us know that even tree-vectorize alone could lead to instabilities, thus our policy will be, from now on, to test packages compiled with graphite and/or tree-vectorize very carefully before pushing them out. In my opinion Sabayon must not become unstable for some optimizations, there are a lot of packages that don't respect good coding practices, this most likely leads to crashes when compiled with higher optimization levels, my guess is that bad coding leads to problems with optimizations, I am aware of some dubious pointer arithmetics and usage on Seven Kingdoms. Thus default CFLAGS will be -O2 alone.
