--- Comment #3 from Jason Vas Dias <jason.vas.dias at gmail dot com> 2012-08-05 11:36:05 UTC --- RE: > Your PC is broken. Comments such as these don't help much. No, only Linux 3.4+ temperature management is. I'm working with the Linux developers to resolve this . Meanwhile, I'm stuck with gcc-4.6.0, which I'd like to do something about. > C only build with 3 stages takes about 18 minutes with -j2 > on my PC. And what type of super-computer is that ? > Compilation of small count of big files is faster than big count of small > files. Not in my experience. Why force such huge memory resource demands ? I guess as usual no help is to be expected from gcc-bugs - I'll have to modify genemit.c myself. One final try before I go modifying genemit.c : Can anyone suggest what state cc1 is in when it shows this 20 minute strace: $ strace -tfp 3863 Process 3863 attached - interrupt to quit 11:10:24
