mstorsjo added a comment. I've bisected a crash in generated code down to this commit. The code that crashes is clean when run in ubsan. The misbehaviour happens across 4 tested architectures (i686, x86_64, armv7, aarch64).
The misbehaviour occurs in this preprocessed source, https://martin.st/temp/seek-preproc.c, compiled with `clang -target x86_64-linux-gnu -c -O3 seek-preproc.c`. The whole failing testcase can be reproduced (on e.g. linux) with these steps: git clone git://source.ffmpeg.org/ffmpeg cd ffmpeg ./configure --cc=clang make -j4 fate-seek-acodec-flac (The failing object file is `libavformat/seek.o`.)
