I am aware of that, but I need it to compile in order to fix the bugs. I had no problem compiling with the 2.6.0 tree. The compiler is created, it barfs when trying to create the RTL files.
It must be the new compiler that crashes. It looks like a game with gdb is needed.

For the compiler I updated the code to follow the changes in other processors so it would compile, there are quite a few changes between 2.6.0 and 2.7.1
As for the RTL the only changes I made was to add support for the processors that I have. The current code only had support for the uc3b1256 which isn't one that I have.
