Crash as I was pasting

I am running emacsclient -t to compose my mail, that is Emacs. I'm using Tilix as my terminal emulator. I pasted some text using Ctrl+Shift+C into the message I was composing and got the following:

I continue to experience a panic when I paste drafted text into aerc's compose window. One workaround I've found is switching over to iTerm2 on my mac. If I use iTerm's "paste slowly" feature, I can usually get the whole thing pasted without the panic. Otherwise, the content begins to paste but after a certain amount the panic occurs.

I put what I could recover from the panic message at https://paste.sr.ht/~exprez135/f0f7051758e89c4ce5c400bd7d9f18eb1a91065e.

I am regularly having the same crash. I avoid this by :read-ing a file in vim, but it's not ideal

P.S. the link above is broken due to the ., https://paste.sr.ht/~exprez135/f0f7051758e89c4ce5c400bd7d9f18eb1a91065e works

~sijmen are you on OSX as well? (or whatever the mac os is called nowdays)

~sijmen 7 months ago

~labrat no, Arch Linux/sway/alacritty/neovim

I’ve experienced this as well a few times recently but haven’t had the chance to debug it at all.

I also experienced it on Manjaro Linux/XFCE/alacritty and xfce4-terminal/neovim and nano.

Steps to reproduce:

  1. Copy a lot of data into your clipboard ( python3 -c 'print("A"*9999)' | clipcopy should do it )
  2. Start aerc, and compose a new email
  3. Directly go to the plaintext editor ( Press Tab two times )
  4. Paste your clipboard and then press enter
  5. Repeat step 4 until aerc crashes
