This setting was recently added in emscripten-core#25581 and it only currently has en effect on pthread-based programs. It is also not compatible with `-sNO_DYNAMIC_EXECUTION` because it depends on starting worker based on JS string. These errors look like this: ``` $ emcc -sCROSS_ORIGIN -pthread -sDYNAMIC_EXECUTION=0 hello.c emcc: error: CROSS_ORIGIN is not compatible with DYNAMIC_EXECUTION=0 ```
