Game crashes when certain text is sent to chat

Hello. Today, I actived the narrator, using CTRL+B. I tried having it read different messages, and went on spamming the chat. A full-length Message containing slashes, beginning with "." worked just fine. Other spamming messages worked just fine as well. The problem started trying to type in "sing". Now, sending "sing" worked just fine. "singsing" too. What didn't work, was to press Enter, sending:

"singsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsingsing"

to the chat. When pressing Enter, I got an error message, saying that the program had crashed. I could either close it, or troubleshoot it. I closed the error window, and so the game was closed as well. I tried again, and the same happened. I tried fewer "sings", and it showed to be a certain amount that crashed it. There had to be many. I dont' know the exact number. As said, I spammed the chat with several other full-length messages. This worked just fine.

I now disabled the narrator, and tried sending the above "singsingsing"+ message again. Everything worked as it should. No crash. I then reenabled the narrator. I sent the same message again, but with no crash. Note that there were several crashes. I did not change the narrator settings between these.

Please understand that I have already searched for similar reports, but did not find any that fits this. Thank you for your time. I'd always be happy suggesting new features.

Thank you for your report!
However, this issue is Invalid.

Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.

+ Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.
+ Any plugin issues need to be addressed to the creator of the plugin or resource pack.
+ If you have problems on large servers, such as The Hive and Hypixel, please contact them first as they run modified server software.

It seems another person has gotten almost the same error message as me. Their screenshot can be seen. I hope you can make this report valid, if that person runs Vanilla Minecraft.

It's also worth mentioning that Optifine should have no impact on the chat. All that it modifies, is rendering, as far as I'm concerned. I also wonder how Optifine works compared to Vanilla. It gives many more fps, and gives options for different ways of rendering textures. A little strange a plugin can raise my fps from 15 to 43, and give a more stable game.

We don't usually allow issues with mods because we can't know what the mod changes, and we can't fix issues within the mods.

Next time this happens, I'd like you to generate a stacktrace using jstack (even if you're still using optifine when it happens; any debug info is better than none). Here's how it would work:

  1. Open task manager

  2. Find the non-responding instance of javaw for Minecraft

  3. Right-click it, and select "Go to details"

  4. Note the value for PID

  5. Select "File", and then "Run new task", and type cmd

  6. Type "cd Documents" (to enter the documents folder)

  7. Type "jstack -F [PID] > jstack_mc-119028_small.txt", replacing [PID] with the PID from earlier

  8. Type "jstack -F -m -l [PID] > jstack_mc-119028_long.txt", replacing [PID] with the PID from earlier

  9. Attach jstack_mc-119028_small.txt and jstack_mc-119028_long.txt (both in your documents folder) to this ticket

Little side note: optifine does change some game mecanics, like grass growing under water.
