Failure writing a module #30

Open tshort opened 6 years ago

tshort commented 6 years ago

This is probably a WebAssembly issue.

Charlotte branch: tshort#julia-0.7-arrays WebAssembly branch: julia-0.7-optimise

using Charlotte: wasm_module 
using WebAssembly: getModule

function mathfun(x)
    2x
end

m = wasm_module([mathfun => Tuple{Float64}])
write("mathfun.wasm", getModule(m))

Here's the error:
