When I normally program in Go with the gopls language server, Emacs
crashes on autocomplete spots. I can't pin down the precise cases when it happens, because it happens spontaneously, but I have learned to type
very fast in order not to toggle autocompletion. It must be mentioned
that I use `corfu' with `corfu-auto-delay' set to 0.5 seconds. I enabled
traces, and inspecting the trace it shows consistently that the last or
so message from the language server is a very long one. Initially, I
filed an issue at gopls:  https://github.com/golang/go/issues/69368 .
However, now it also crashes on autocomplete with Sly! I doubted it is
something with emacs initially, thinking the gopls process was somehow
crashing emacs. Now, however, I am pretty sure it is something with
emacs.
 
I use Arch linux, emacs version 29.4-2, installed with the emacs-wayland
package (with native compilation and PGTK enabled). My computer's specs:
CPU: Ryzen 5 4500
GPU: AMD ATI Radeon RX 6400/6500 XT/65
16GB of RAM
 
Running emacs on wayland with GNOME.
 
If I can provide better information, please tell me what to do.

Could you try building Emacs from the master branch?

IIRC at least one crash bug that manifested with Corfu had been fixed in 
this release cycle, but it's hard to tell whether that it was the same one.

And if the problem persists on master (or if you are unable to build
it), please show a backtrace from the crash by running Emacs under
GDB, and when it crashes, typing "thread apply all bt" at the GDB
prompt.

The above assumes that by "crashing" you mean the Emacs process hits a
fatal error and is terminated by the OS.  If that's not what you mean,
then please tell what you mean by "crashes".

Thanks.

Thanks, I'm therefore closing this bug.
