Re: [PATCH v4 2/2] ci: compile "linux-gcc-default" job with -Og

I think you could do it with:

			if (data)
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wuninitialized"
				munmap(data, mtimes_size);
#pragma GCC diagnostic pop

which is...ugly. There's a _Pragma() operator, too, which I think would
let you make a macro like:

			if (data)
				SUPPRESS("-Wuninitialized", munmap(data, mtimes_size));

which is maybe slightly less horrific? Still pretty magical though.

But if the alternative is to do none of that, and just continue to avoid
looking for warnings with -Os, I prefer that.

Oh, we are in agreement.  Such effort to annotate code and tolerate
inconvenience is better spent elsewhere but expertise and competence
are not as fungible as I wish them to be ;-)

Thanks.
