Expecting:

{
    sym.imp.printf("Hello world\n");
    return 0;
}

Still happens with the latest Rizin & Rz-ghidra (https://github.com/rizinorg/rizin/commit/ead601655cb8ba3655be278426ad8d6e60382227 and https://github.com/rizinorg/rz-ghidra/commit/0c9ab921afa034cf7186821712d988d06190e07e respectively)
