--- Comment #3 from Jeffrey A. Law <law at gcc dot gnu.org> --- Unfortunately, you're likely going to have to do much of the debugging yourself. spec2k6 is licensed software that everyone does not have access to. What I would recommend would be to use qemu's remote debugging stub. This allows you to connect gdb to the qemu running the program. From that you can hopefully start to track down what code is mis-behaving. Good luck
