问题
I am having a weird problem with boost spirit X3 (v1.69) in combination with MS VS2017.
I am getting compiling errors in well formed structures. When I use the same code block in gcc and clang through Coliru or Wandbox, the source compiles and everything goes right.
But when I use that same code in VS 2017, compiling errors appears until I comment an 'omit' sentence.
Please, any help with this?

I provide links to both Coliru / Wandbox to show what I am talking about:
https://coliru.stacked-crooked.com/a/3f9293c8ef0da3c0
https://wandbox.org/permlink/hoT6NRNg5JMq32B9
I would be glad if anyone tries to propose an alternative paarsing rule that I could test in VS 2017.
Thank you in advance.
