It's still not 100% clear why DGROUP has to be defined explicitely in this special case. Because OW WASM's -ml cmdline option should declare the large memory model, similar to Masm's ".model large" directive. And the large memory model is supposed to automatically

1) define group DGROUP and segment _DATA
2) put _DATA into DGROUP
3) add ASSUME DS:DGROUP
