This causes panics for me when building ports in the tmpfs-backed tinderbox. Easily reproducible: 1) ./tc tinderbuild ... -b "$@" 2) tail -f .../tmp/make.log4 # on the adjacent console 3) wait until the build job finishes 4) ^C in the "tail" window -> crash ... __mtx_lock_sleep() tmpfs_free_node() tmpfs_fo_close() _fdrop() closef() fdescfree_fds() fdescfree() exit1() sigexit() postsig() ast() doreit_ast() ./danfe _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
