Infinite loop in compilation (with AxisArrays)

[iamed2]

I tried to distill this so it didn't require AxisArrays with no luck. It seems to be a pretty complex interaction.

using AxisArrays

A = AxisArray([  1  4  7  10  13
                 2  5  8  11  14
                 3  6  9  12  15], :y, :x)
for C in (A,)
    for op in (sum,)
        C1t = op(C, Axis{:y})
    end
end

Making A const fixes it. Assigning the tuples to variables fixes it. Calling op with a numerical dimension instead of an Axis fixes it.

This happens on master (80369bf7b4 as of this post) and is not SIGINTable.

This does not occur on v0.6.0-rc3

So can it be closed then? What's the action here? Bisect to figure out what fixed it?

[iamed2]

No, I mean it's upstream from 0.6, on master.

A bisect might work to find out what introduced this, but since it's such a finicky example that might not find the actual underlying bug.

Is this fixed by #21933 now?

[iamed2]

Yep, looks like that did it 🎉
