[Openmp-dev] Debugger default off please

[C Bergström]

Can you give an example of how this will help an end user debug his code?

Side note: having docs and examples for new features may help
developers and end users understand.

Personally, I think for day-1 features it's way more conservative to
leave them off by default unless there's a very compelling reason to
turn them on-by-default. I counter argument to this is possibly
something which really must get tested and exposed to as many users as
possible (this could be such a feature)

Thanks
