Any reason t1 cannot be removed and the second resize be applied to t0?

27 ↗(On Diff #5187)

Same question as above.

28 ↗(On Diff #5187)

shouldn't this be t1?

You want to check the destruction of vector that are within and out of bounds with the preallocated buffer.

28 ↗(On Diff #5187)

Probably. It's definitively t0 in core.

deadalnix updated this revision to Diff 5197.Sep 30 2018, 17:53

Fix t0.clear() => t1.clear()
