Hi, randomly we get lockups during termination of DirectFB version 1.2.3. We did not see this in earlier versions of the same code. As far as we know we have the expected exit handling and it worked fine, without complaints, before.
When I connect a gdb against the locked process I get the following backtrace: --------------------------------------------------------------------------------- (gdb) bt #0 0xb7f97424 in __kernel_vsyscall () #1 0xb7c5aca9 in __lll_lock_wait () from /lib/i686/cmov/libpthread.so.0 #2 0xb7c560d3 in _L_lock_291 () from /lib/i686/cmov/libpthread.so.0 #3 0xb7c55b36 in pthread_mutex_lock () from /lib/i686/cmov/libpthread.so.0 #4 0xb7d63866 in pthread_mutex_lock () from /lib/i686/cmov/libc.so.6 #5 0xb7c7131e in fusion_reactor_detach_global () from /usr/local/sdk/directfb/custom/local/directfb-1.2.3/lib/libfusion-1.2.so.0 #6 0xb7f728dd in dfb_input_detach_global () from /usr/local/sdk/directfb/custom/local/directfb-1.2.3/lib/libdirectfb-1.2.so.0 #7 0xb7f87fd0 in dfb_windowstack_destroy () from /usr/local/sdk/directfb/custom/local/directfb-1.2.3/lib/libdirectfb-1.2.so.0 #8 0xb7f7700a in context_destructor () from /usr/local/sdk/directfb/custom/local/directfb-1.2.3/lib/libdirectfb-1.2.so.0 #9 0xb7c70ea6 in object_reference_watcher () from /usr/local/sdk/directfb/custom/local/directfb-1.2.3/lib/libfusion-1.2.so.0 #10 0xb7c71de0 in fusion_ref_down () from /usr/local/sdk/directfb/custom/local/directfb-1.2.3/lib/libfusion-1.2.so.0 #11 0xb7f2effa in IDirectFB_Destruct () from /usr/local/sdk/directfb/custom/local/directfb-1.2.3/lib/libdirectfb-1.2.so.0 #12 0xb7f2f12c in IDirectFB_Release () from /usr/local/sdk/directfb/custom/local/directfb-1.2.3/lib/libdirectfb-1.2.so.0 #13 0x08048f21 in main (argc=Cannot access memory at address 0x80 ) at blit.c:92 --------------------------------------------------------------------------------- The line at row 92 is my DirectFB release: 92 dfb->Release( dfb ); Has anything changed in this area?
