[mineiro]

Well, just sharing that ml64 can create empty .exe files. Is this a feature?

What would be the purpose? - Also I'm sure most assemblers can do this.

Below is just a report of one error:

Do you really suggest to get something useful from this?

BTW: jwasm is the way to go - at least for x64

Well Sr qword, if you are working with ml64 and are inside a big project, you can receive errors and do not know where the problem is. This is the intention of this post, maybe someone receive that errors, and can know about how to generate the same error to find a mistake. While the first example show you about where the problem is, the example below simply do not show you where the error happened. In a big project, is easy you put a name that was used before to reference something or someplace. If you work alone, this probably does not occurs, but I'm working togheter.

I agree with you about jwasm, but I do not forget about others assemblers like yasm.
