This looks like a bug in the Go compiler!?

I wonder if fyne-cross is turning on CGO and triggering a compiler path that is not expected as wasm is not actually a different platform in the same way that most of our cross compiling is?

GOOS=js GOARCH=wasm fyne package -os web

Just FYI you don't need GOOS and GOARCH, fyne package does it all for you.
