Does the problem go away if you change the build flags to just target_cpu="x64" and maybe just is_component_build = false? If so can you try adding them back in one at a time to see which one triggers it (I'd probably start with v8_monolithic since the v8_enable_* flags there seem unlikely to be the cause?
