The game will unpredictably crash. This has happened during the splash screen as well as during actual gameplay.

I root-caused this to a change in jemalloc version. Prerelease 3 downgraded to LWJGL 3.1.6 (which includes jemalloc 5.1.0). Forcing the game to use lwjgl 3.2.1 (which includes jemalloc 5.2.0) solves the issue. See the details I wrote in MC-148505.

@md_5 did you mean Ubuntu 18.10 or 19.04? I can confirm this on 19.04 as well.

I have confirmed that this issue occurs under Ubuntu 16.04, JRE 8 revision 201. Only started happening with 1.14 pre-release 5. Changing the JVM argument from -Xmx2G to -Xmx4G solved or worked around the issue with the client crashing during the splash screen loading phase.

I can confirm for Linux Mint 19 Tara with 1.14 pre 5.
I used the following 1.14test.json to use the newer lwjgl 3.2.1 as Sargun explains above: https://pastebin.com/XZkdw9Tw which is a workaround for the time being to allow me to play.
Steps for workaround:
1. Go to your minecraft folder (~/.minecraft)
2. Go in the versions folder
3. Copy '1.14 Pre-Release 5' folder to '1.14test'
4. Rename the .jar to '1.14test.jar' and the .json to '1.14test.json'
5. Paste from the pastebin link I gave above to replace the 1.14test.json file.
6. In Minecraft Launcher, go to 'Launch Options' and enable 'Advanced Settings'
7. Click Add new
8. Type in a name, such as '1.14 v5 patched' or 'Custom'
9. Under version, select 'snapshot 1.14test'
10. Click Save
11. Click News at the top to go back to main menu
12. Click the up arrow at the bottom to select the new launch option you just made.
13. Click Play, and you should be all set!

I have the same problem in 1.14 Pre-Release 5 (on Kubuntu 18.04 / 64bit).
Probably unrelated, since I can't reproduce it again, but it happened twice after a command like this (one time directly after, one time minutes later):
/summon minecraft:skeleton ~ ~ ~ {HandItems:[{id:"minecraft:barrier",Count:1b}]}

Confirm on 14 pre 5.

Confirmed 14pre5. Exact same as above. Changing to lwjgl 3.2.1 as above seems to have solved it temporarily.

In general, one of the workarounds we have employed locally is to use lwjgl-jemalloc 3.2.1 with the rest of lwjgl being at 3.1.6 on Linux - this hasn't caused any issues so far, and may be a consideration-worthy option.

Same problem on Manjaro with 1.14 Pre-Release 5.

Also confirmed on 1.14, seems like this wasn't fixed on macOS
