Hi all, > Well, Martin compiles and _runs compiled tools during the office build. > So libkse can reboot the machine :) This is definitly true. The build tools heavily use threads, and I always had some of the tools breaking with either libc_r or now libkse, libthr. We found one bug this way for libkse. > BTW, I can reliably crash libkse programs on a SMP box using a trivial > code snippet. It looks like kernel is trying to lock an uninitialized or > freed mutes and dies with trap 12 while holding a sched_lock spinlock. > Not a pretty sight. The offending line is kern_mutex.c:598. Sorry, no > backtrace yet thanks to schedlock. I just finished a build of OpenOffice and it seems to run fine ! What about HTT ? Can we use that to emulate several cpu's ? Martin
