Well, 20 minutes of memtest86+ doesn't show any errors, thankfully.

Thanks, I've just checked that. The link is indeed pointing to the
correct kernel. The only thing odd about it is the kernel has 777
permissions rather than 755, dating from April when I was messing with
the kernel's soft scrolling. But that couldn't cause gcc to segfault,
surely?
