--- Comment #17 from Wan-Teh Chang <[email protected]> ---
I am a maintainer of the aom library (libaom). This crash was reported to us in
https://aomedia.g-issues.chromium.org/issues/466322847.

With the help of the user who reported the bug to us, I tracked down the bug.
It suffices to read from
https://aomedia.g-issues.chromium.org/issues/466322847#comment13 on. In
summary, the libaom.3.dylib file in digiKam 8.8.0 for macOS arm64 was built
with an aom Portfile that turns off runtime CPU detection in libaom.3.dylib, so
libaom.3.dylib blindly executes SVE instructions, which are not supported on
Apple Silicon. To fix this bug, cherry-pick the aom Portfile bug fix in
https://github.com/macports/macports-ports/commit/f64e746df425a078b13da45ae292776cb03cc6f5.
