Damage when teleported to Nether

I came here to create a bug for this. It was happening on every teleport for me, both into and out of nether. I had created the portal completely embedded in rock except for one half of one face.

I confirm this too. It's suffocation damage.
In the beginning I thought it was because at the other end the portal was built between walls in a corridor. But it is not because it also happens when the portal is built in spacious spots. In SMP I always receive half heart suffocation damage.

I can confirm this, i got a netherportal surrounded by stone left right top and bottom (front and back are free) and i get o.5 damage every time i go trough and i sometimes get stuck in the wall!

This still happens in 1.4.5, to me, but inconsistently: some portals do me damage, others don't.
For instance the one that damages me, that I know of:

nether portal at x:-2020 y:113 z:-208/-207, linked to overworld at x:-16162 y:48 z:-1662/-1663

Ones that do not:

nether portal at x:-2048 y:120 z:-222/-223, linked to overworld at x:-16380/-16381 y:77 z:-1776

nether portal at x:-2049 y:120 z:-166/-167, linked to overworld at x:-16389/-16390 y:57 z:-1337

(y values are foot position when standing in the portal)

None of these are against walls except the first overworld portal. No nether portal faces a wall.

(No idea if it's related to coordinates, but since certain portals always damage me, and certain portals never do, I figured hey.)

The portals that used to damage me, don't anymore as of 1.4.7. Anybody else?

This bug is now present in 1.8-pre3 since dinnerbone fixed MC-3. I tested my portal created in a snapshot prior to the 1.8 release, and I now take damage after I get to the nether, depending on which of the two blocks I stand in when entering from the overworld.

Things to note: Prior to the fix for MC-3 when entering the other dimension when using a portal, you would still be in the portal, now you are no longer in the portal. I believe that this is the source of the damage bug as the player placement is now outside the portal and sometimes this might be inside a block. This could be fatal for the first trip to the nether if you're over lava so I really hope this bug gets escalated!

Both portals are facing north-south. When I enter the overworld portal standing on the left side while facing south, I exit the nether portal on the left side but one block over and forward, facing north. If I enter the overworld portal standing on the right side while facing south, I exit the nether on the left side, but TWO blocks over and forward, which for this portal was a wall so I took damage. My portals are the traditional size of 5 tall by 4 wide with the interior of the portal being 3 tall by 2 wide.

And here is some more information - One of my portals in the nether had the four blocks immediately in front of the portal (at the same level as you would be standing on the obsidian of the portal floor) filled with a half slab, which means before this breakage, you would exit the portal and then rise up a half slab height. After the bug was introduced, you now go somewhere else, which in my case is below the portal and into the lava pool underneath 😞

@@unknown: This is MC-73504

This is happening for me in the linux version of the latest snapshot (15w42a). It only happens on linux (I've tried mac and windows also) and only when leaving the nether on one of my portals. I take between 1 and 5 hearts of damage. Let me know if I need to create this as a separate bug.

@unknown: This is most likely a separate issue. If you can recreate it in a world created in 15w42a, please create a new ticket.
