error: function signature mismatch: emscripten_memcpy_big

[Ciantic]

I'm using simple C file:

int answer() {
    return 1234;
}

In plain Rust project and compiling it with emscripten / emcc with a call:

$ cargo build --target wasm32-unknown-emscripten

wasm-ld: error: function signature mismatch: emscripten_memcpy_big
          >>> defined as (i32, i32, i32) -> void in emscripten/cache/sysroot/lib/wasm32-emscripten/libc-debug.a(emscripten_memcpy.o)
          >>> defined as (i32, i32, i32) -> i32 in emscripten/cache/sysroot/lib/wasm32-emscripten/libstandalonewasm.a(standalone.o)

Is this bug in emscripten or am I doing something wrong? It seems weird that signature would differ.

I got an answer elsewhere, it's a bug in emscripten and fixed in here:

#17212

Not yet in the emscripten repo.
