For example with sysutils/fusefs-encfs. When it starts, it enters fuse_main(). And when FS is unmounted, sometimes, main thread hangs in fuse_main(), all threads being stuck in pthread_cleanup_pop(). Here is a backtrace : (gdb) thread apply all bt Thread 2 (Thread 802618000 (LWP 100408/encfs)): #0 0x0000000801da267c in pthread_cleanup_pop () from /lib/libthr.so.3 #1 0x00000008008c8b1b in fuse_session_loop_mt () from /usr/local/lib/libfuse.so.2 #2 0x00000008008cd8c2 in fuse_loop_mt () from /usr/local/lib/libfuse.so.2 #3 0x00000008008d0618 in fuse_main_real () from /usr/local/lib/libfuse.so.2 #4 0x000000000040a246 in ??
