qemu-arm segfaults

[MastaG]

Hi there, I'm using meta-browser rev: https://github.com/OSSystems/meta-browser/commit/41d3e6baea266a652c2d4dbdeca767a3054e13e8 To build chromium-ozone-wayland for 32bit arm. My openembedded-core, meta-openembedded, meta-rust and bitbake layers are all on todays master branch.

Build Configuration: BB_VERSION = "1.40.0" BUILD_SYS = "x86_64-linux" NATIVELSBSTRING = "fedora-29" TARGET_SYS = "arm-oe-linux-gnueabi" MACHINE = "odroid-xu3" DISTRO = "odroid-os" DISTRO_VERSION = "release" TUNE_FEATURES = "arm vfp cortexa15 neon vfpv4 thumb callconvention-hard" TARGET_FPU = "hard"

My GN flags: use_cups=true ffmpeg_branding="Chrome" proprietary_codecs=true use_v4l2_codec=true use_v4lplugin=true use_linux_v4l2_only=true is_component_build=false use_atk=false use_gnome_keyring=false use_jumbo_build=false use_kerberos=false use_pulseaudio=true use_system_freetype=true use_system_libjpeg=true closure_compile=false host_pkg_config="pkg-config-native" is_debug=false is_official_build=true use_custom_libcxx=false use_lld=false symbol_level=0 enable_remoting=false enable_nacl=false use_sysroot=false treat_warnings_as_errors=false is_cfi=false fieldtrial_testing_like_official_build=true google_api_key="" google_default_client_id="" google_default_client_secret="" custom_toolchain="//build/toolchain/yocto:yocto_target" gold_path="" host_toolchain="//build/toolchain/yocto:yocto_native" is_clang=false clang_base_path="/media/data/home/mastag/odroid-oe-core/build/tmp/work/cortexa15t2hf-neon-vfpv4-oe-linux-gnueabi/chromium-ozone-wayland/72.0.3626.119-r0/recipe-sysroot-native/usr/bin" clang_use_chrome_plugins=false linux_use_bundled_binutils=false target_cpu="arm" use_gold=true v8_snapshot_toolchain="//build/toolchain/yocto:yocto_target" use_cups=true ffmpeg_branding="Chrome" proprietary_codecs=true use_v4l2_codec=true use_v4lplugin=true use_linux_v4l2_only=true use_ozone=true ozone_auto_platforms=false ozone_platform_headless=true ozone_platform_wayland=true ozone_platform_x11=false use_xkbcommon=true use_system_libwayland=true use_system_minigbm=true use_system_libdrm=true enable_hangout_services_extension=true use_wayland_gbm=true enable_widevine=true arm_float_abi="hard" arm_fpu="neon-vfpv4" arm_tune="cortex-a15" arm_version=7

Everything works up to the point where it has to use the qemu-wrapper to build some native parts of the browser. This seems to segfault. See the attached log. log.do_compile.zip

Any ideas?

I have seen infinite hangs but not crashes. I think this is definitely something to look into qemu itself.

this has been fixed by upstream oe-core. they've switched the default arm target to armv7 and now it works.
