I can confirm that this still happens in 1.8.7. It does not occur if the command is ran by a command block or from the console.
I can confirm the command used does not cause the console to be spammed.
I can also confirm "/summon Item ~5 ~ ~" (relative co-ords to make sure you don't pick the item up) still spams the console on 1.8.7.
Attempting to place a ladder on a ladder will make it attach to the wall, signs float. When placing a vine on a block that already has a vine it places the vine on the vine block, much like placing water on a block that already has water.
When pistons push the jungle logs that cocoa beans are on, sometimes they pop off and sometimes they don't. This is the same for a redstone torch placed on the side of a block.
I can confirm this
This seems to have solved the crashing problem! Thanks!
The bounding box flashing problem is still there though, should I submit another bug report for it?

--- END ERROR REPORT 7b18e325 ----------
There are multiple files but none for today, It crashed like this twice today.
Yes. I tried this both with no mods installed and optifine installed, in creative and survival.
Sometimes it shows a "Minecraft not responding" from windows but other times it closes without any error.
After some more experimentation I can see what you mean @Noah Larkin.
Here is the results from testing version 1.8.7:
Singleplayer: The spawner does not cause anything to appear in the console, but "/summon Item" causes ~4 messages of "[Server thread/ERROR]: Item entity # has no item?!".
Singleplayer (open to LAN): Same as Singleplayer.
Multiplayer Server: The spawner does not cause anything to appear in the console, but "/summon Item" causes the server log to be spammed with "[<time>][Server thread/ERROR]: Item entity # has no item?
[media]" (different value to server thread).
The server continues to be spammed if the player logs out from the server. The client still gets spammed upon joining the server. The spamming stops when the item is either picked up, despawns.
Stopping and restarting the server causes the spamming to stop.
