Hi, After trying to figure out how to solve the problem I have on my own, I'd like to submit it to you, to get some hints. Here it is: almost all programs related to kde (kdevelop, kghosviewer, kile, ...) and gaim are segfaulting, because of a problem which seems to be related to pthread. Please note that everything else is working fine : xfce-4.4, anjuta, firefox, etc... FreeBSD 7.0-CURRENT #6: Fri Feb 2 13:47:26 EST 2007 root@greg:/usr/obj/usr/src/sys/MYSMP i386 running gdb kile : Program received signal SIGSEGV, Segmentation fault. [Switching to LWP 100060] 0x29d0f1f9 in pthread_join () from /lib/libpthread.so.2 (gdb) bt #0 0x29d0f1f9 in pthread_join () from /lib/libpthread.so.2 #1 0x29d0374a in pthread_self () from /lib/libpthread.so.2 #2 0x29d03dfc in pthread_rwlock_unlock () from /lib/libpthread.so.2 #3 0x29d0f2b2 in pthread_join () from /lib/libpthread.so.2 #4 0x29d0374a in pthread_self () from /lib/libpthread.so.2 #5 0x29d03dfc in pthread_rwlock_unlock () from /lib/libpthread.so.2 #6 0x29d0f2b2 in pthread_join () from /lib/libpthread.so.2 #7 0x29d0374a in pthread_self () from /lib/libpthread.so.2 #8 0x29d03dfc in pthread_rwlock_unlock () from /lib/libpthread.so.2 ... and it goes far, repeating it ad vitam. (using ktrace and kdump, wc -l outputs 637047) By the way, the equivalent in the ktrace part is : 2913 kile CALL getpid 2913 kile RET getpid 2913/0xb61 2913 kile CALL getpid 2913 kile RET getpid 2913/0xb61 2913 kile CALL getpid 2913 kile RET getpid 2913/0xb61 Same for kdevelop-bin and all the kde-related who segfault (because some rare k(something) work, like konsole oder KDE System Guard) For gaim, the error message is a bit different, but bt gives the same output : Program received signal SIGSEGV, Segmentation fault. [Switching to LWP 100079] 0x28b38d3e in sysctl () from /lib/libc.so.6 (gdb) bt #0 0x28b38d3e in sysctl () from /lib/libc.so.6 #1 0x28a852b2 in pthread_join () from /lib/libpthread.so.2 #2 0x28a7974a in pthread_self () from /lib/libpthread.so.2 #3 0x28a79dfc in pthread_rwlock_unlock () from /lib/libpthread.so.2 #4 0x28a852b2 in pthread_join () from /lib/libpthread.so.2 #5 0x28a7974a in pthread_self () from /lib/libpthread.so.2 #6 0x28a79dfc in pthread_rwlock_unlock () from /lib/libpthread.so.2 I experience these problems for more than a week now. Everything is up-to-date on my system (src + ports) - last cvsup a few hours ago. I recompiled everything a few time. As I did not see feedback on forums or on mailing lists, I assume I am the only one who has this problem. Which makes me feel a bit lonely ;) Could you please me help me ? Also, I would be glad to provide any further information like dmesg, bt, ktrace, whatever, ... Thanks ! Gregory
