#11332: ffio_open_whitelist leaks memory ----------------------------------+---------------------------------- Reporter: oarfish | Type: defect Status: new | Priority: normal Component: avformat | Version: 7.1 Keywords: leak | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+---------------------------------- I suspect that ffio_open_whitelist is leaking an URLContext. In this line, a context is declared https://github.com/FFmpeg/FFmpeg/blob/7c1e732ad2e240af5afe9ffea443c91bb233aa... and then allocated by ffurl_open_whitelist at https://github.com/FFmpeg/FFmpeg/blob/7c1e732ad2e240af5afe9ffea443c91bb233aa... However, I don't see it being freed anywhere. In my program, this causes the leak sanitizer to report a leak: {{{ Indirect leak of 234 byte(s) in 1 object(s) allocated from: #0 0x7faaaa89565f in __interceptor_posix_memalign ../../../../src/libsanitizer/lsan/lsan_interceptors.cpp:110 #1 0x557e4562f3df in av_malloc libavutil/mem.c:107 #2 0x557e4562f7f3 in av_mallocz libavutil/mem.c:258 #3 0x557e458b85d0 in url_alloc_for_protocol libavformat/avio.c:139 #4 0x557e458b9271 in ffurl_alloc libavformat/avio.c:356 #5 0x557e458b92e6 in ffurl_open_whitelist libavformat/avio.c:369 #6 0x557e458b988c in ffio_open_whitelist libavformat/avio.c:480 #7 0x557e4588b767 in io_open_default libavformat/options.c:153 #8 0x557e45875a27 in init_input libavformat/demux.c:178 #9 0x557e45875d35 in avformat_open_input libavformat/demux.c:248 }}} I did not manage to reproduce this repro this yet in a minimal executable, will update once i can. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11332> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
