Hi,

Well, yes of course, that takes care of that problem, which eventually would need to be done.

OTOH, does this then result in a dead-code warning? Maybe not from the compiler, but then from static code analysis.

So this was more to see what would happen then.

Thanks,

Jaap

Hi,

Well, you might as well remove that function (asterix_parse_re_field) from compilation, since it doesn’t seem to be used…

Thanks,

Jaap

Hi,

What happens if you pull again?

Pulled as hard as I could. No go.

Y.

 

Thanks,
