I believe this is fixed upstream by: commit b9c6afd3a7c7ac302b47e70b5c745b84cb35f188 Author: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com> Date: Wed Apr 2 15:30:20 2025 +0300 meson: disable SIMD blake optimisations on x32 host On X.org startup libgallium crashes on x32 hosts inside blake3_hash_many_sse41(), most likely because of the different pointer size. Disable SIMD blake implementation if x32 is detected. Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/34453>
