[[bad mustMatch:]]: error while compiling to wasm

[Hüseyin Akbaş]

Hi I was trying to build wasm code via ldc and binaryen. I saw 
how to do it in a c++ tutorial.

My source code is:

import std.stdio;

extern(C) int main()
{
	writeln("Edit source/app.d to start your project.");
   return 0;
}


I compile with the following:
ldc2 app.d -output-s
s2wasm app.s > app.wast

While compiling to s, everyhing is fine but s2wasm it gives this 
error:
<< set >>
[[bad mustMatch:]]:
==========
_main:
	.cfi_startproc
	pushq	%rbp
Lcfi0:
	.cfi_def_cfa_offs
==========

It is something related to the D structure? How can I fix this?

Thanks
