>I don't think this is related to logging, I'm getting it even without logging enabled. You're getting a different crash, it just happens to be using the ioctl syscall as well. The one in this bug is caused by the logging code calling isatty/tcgetattr, see comment 2. We have code to handle that (so I guess comment 7 is wrong too in terms of complexity), but it's only in the content policy. It wasn't added to the RDD process when ffmpeg was moved there: https://searchfox.org/mozilla-central/source/security/sandbox/linux/SandboxFilter.cpp#1288 Conversely none of the code knows about DRM_IOCTL_VERSION
