Crash when inserting ✅

[dduenker]

Description :octocat:

Inserting ✅ into a new buffer crashes emacs, when i have the unicode-fonts layer activated.

Reproduction guide :beetle:

• Start Emacs
• Open new buffer
• insert ✅
• move cursor in front of ✅

Observed behaviour: :eyes: :broken_heart: Emacs crashes

Expected behaviour: :heart: :smile: Emacs does not crash

OS: Arch Linux 5.6.11-arch1-1 Emacs: 26.3-1 Spacemacs devel commit d0f5477c323ef6600e29d22b75d876c49916b3f4

Backtrace :paw_prints:

Can't reproduce on macOS with GNU Emacs 26.3 (build 1, x86_64-apple-darwin18.5.0, Carbon Version 158 AppKit 1671.4) of 2020-03-24

[dduenker]

Well, it says X protocol error in the crashlog. Unless you are running X on your macOS, reproduction should be hard to do.

Then why do you report this bug here if you know it is a X problem?

[dduenker]

Ah well, i have no idea, why this only occurs in emacs and so far only with this emoji. Somehow emacs appears to be sending something strange to X. I have no idea, whether it is emacs, or gtk at fault. But i guess it is not X. Thanks for testing btw. :)

@dduenker you need to provide some more information about your issue. Especially we require proper step by step instructions to reproduce your issue.

I have now entered a new buffer (opens in fundamental-mode) and there inserted :white_check_mark: via SPC i ewhite_check_mark. I have moved the cursor around but it did not kill my emacs. I have done the same with org-mode and it works flawlessly too.

Without more information I would assume this to be an issue between emacs and X. In this case your best bet would be to construct a minimal reproduction on vanilla emacs. If this reproduces your error you should open a bug upstream. If not it may be a side effect of one of the packages spacemacs loads. In this case you need to reduce the number of layers in your dotfile and see when the issue is gone. We can then have a more closer look at the layer in question.

[dduenker]

I guess it has something to do with the used fonts. On the computer where it crashes i see the checkmark on green background. On another one it is just black and white and emacs does not crash. Minimal spacemacs config with just unicode-fonts additionally enabled suffices for the crashing. I guess i have to figure out, what is going on with the fonts.

[dduenker]

Some updates later and emacs 27: issue seems to have vanished.

[silky]

is it back in 28 @dduenker ? i seem to have a similar issue ....
