I'm chasing an issue where compiling > with 4.7.[01] breaks but 4.6.2 is OK, wondering if we're chasing the same thing. I do not remember when I upgraded from lenny to squeeze. It the previous gcc was lenny's, it was gcc version 4.3.2 (Debian 4.3.2-1.1). The gcc in current stable (squeeze) is gcc version 4.4.5 (Debian 4.4.5-8). Since the old laptop is somewhat slow for following unstable, I have not tried any newer gcc version on that machine, and it has been compiling its own kernels for stress-testing purposes. So it's probably not related to gcc 4.6->4.7 changes. -- Meelis Roos (mroos@linux.ee)
