Summary of the bug:
Any build of ffmpeg/ffprobe from e504247db6edb1cb47a9c562277f6e671f4bde1d
or onwards results in segfault 11 when LTO is enabled on MacOS arm64 (M4
base model). Specific commit using git bisect. Big buck bunny is used as
an example, but I can confirm the segfault occurs on a wide range of media
types and codecs (including mp3 audio).
How to reproduce:
{{{
$ ./configure --enable-lto --disable-doc --disable-htmlpages --disable-
podpages --disable-txtpages
$ make
$ ./ffprobe big-buck-bunny.mp4
Segmentation fault: 11
# environment
$ clang --version
Apple clang version 16.0.0 (clang-1600.0.26.6)
Target: arm64-apple-darwin24.3.0
Thread model: posix
$ uname -mrs
Darwin 24.3.0 arm64
24.3.0 Darwin Kernel Version 24.3.0
}}}
