For future reference: events is cleared at the end of this inner loop, so its actual maximum capacity is 3. Even ignoring the clear(), reserve() does not grow the vector by the specified amount, it increases the capacity to the specified amount—so you would need to reserve events.size() + e12 - i12 instead, if you were to even bother.
Luckily, this file is gone now, so this particular instance doesn't matter. But we should be more careful going forward.

@cebtenzzre, good catch. More reviewers there are, lower chance making a mistake, you're right.
