thanks for the '-fno-rename-registers' trick, something like that is not obvious to beginners. I tried with 4.4, but virtual memory usage went to 9Gb, so I'll have to run it on a larger machine. I can't remember seeing this with 4.3, but I'll test. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38474
