This has been around since, forever I believe. Its more a case of Dwarven Stupidity.

From the sound of it, your dwarves channeled themselves in with no way out, except down.

In previous versions, my dwarves would never channel out a tile while standing on it unless there was no other option. This is probably caused by dwarves assuming there will be a nice, safe ramp when they finish digging, but end up falling through the void to their deaths.

This seems to be the same case though. There was nothing left to dig except the tile under their feet, so they dug it away. It'd happen the same way in 40d.

Just the other day I had one of my dwarves dig a hole under themselves in the middle of a long vertical axis shaft I'm intending to use to power my magma pump stack. Said dwarf ended up splattered all over the rock floor about ten levels below.
And this he did with a perfectly valid example of solid ground right next to him where he could have stood instead while digging the channel.
I was mostly amused by this though, even if it was a bit sad to lose a legendary miner to such a fate.

Are you sure he was indeed standing on the place he was digging, rather than that he merely walked onto the empty space he created thinking there was a ramp? I'll have to test this one out sometime.

I've had this happen, although I did not observe if they were channeling under themselves, or just walking into the freshly channeled space. If there is an open space below the floor you are channeling dwarves will occasionally decide to fall through. 31.03.

In 40d you'd often see dwarves channel floors out from under each other, but I never once saw a lone miner channel out the tile he was standing on if there was an adjacent tile available to work from. This seems to be a bug introduced with the change to the channeling designation; even though dwarves are still able to channel from an adjacent tile, standing on the designated tile to do the job is no longer the last resort.
