This causes aborts. I suggest you test it with a fuzzer example: Program received signal SIGABRT, Aborted. 0x00007fffefeaec37 in raise () from /lib/x86_64-linux-gnu/libc.so.6 (gdb) bt Python Exception <type 'exceptions.ImportError'> No module named gdb.frames: #0 0x00007fffefeaec37 in raise () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007fffefeb2028 in abort () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x000000000042bf71 in strict_pthread_join (thread=0, value_ptr=0x0) at ./libavutil/thread.h:55 #3 0x000000000042d412 in ffmpeg_cleanup (ret=1) at fftools/ffmpeg.c:526 #4 0x00000000004251a8 in exit_program (ret=1) at fftools/cmdutils.c:139 #5 0x000000000043f152 in main (argc=6, argv=0x7fffffffe3a8) at fftools/ffmpeg.c:5032 [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB While the State exists there can be no freedom; when there is freedom there will be no State. -- Vladimir Lenin
