Hello, On a couple boxes, after upgrading from 6-STABLE to RELENG_7, a fair number of apps segfault on execution even with compat6x installed. Is this related to the libthr changeover with 7? I don't see anything in a (quick) check of list archives or in UPDATING. A backtrace shows: Program received signal SIGSEGV, Segmentation fault. [Switching to LWP 100140] 0x287469d9 in pthread_join () from /lib/libthr.so.3 (gdb) bt #0 0x287469d9 in pthread_join () from /lib/libthr.so.3 #1 0x28743c94 in pthread_self () from /lib/libthr.so.3 #2 0x28743f5e in pthread_rwlock_timedwrlock () from /lib/libthr.so.3 #3 0x28746bf1 in pthread_join () from /lib/libthr.so.3 #4 0x28743c94 in pthread_self () from /lib/libthr.so.3 #5 0x28743f5e in pthread_rwlock_timedwrlock () from /lib/libthr.so.3 #6 0x28746bf1 in pthread_join () from /lib/libthr.so.3 #7 0x28743c94 in pthread_self () from /lib/libthr.so.3 #8 0x28743f5e in pthread_rwlock_timedwrlock () from /lib/libthr.so.3 And so on ad infinitum. I've recently reproduced this with w3m and svn. Recompiling the app fixes the problem, so I don't mind much, but this seems like it will bite people, and it would be no fun on a production server. Thanks, David
