Closed searene closed 3 years ago

searene commented 3 years ago

Describe the bug Emacs sometimes crashes when used with fcitx. The frequency is about every few days. I've attached gdb to it while crashing and got the following backtrace:

Seems like it's due to xim. I tried to disable xim by adding the following line to ~/.Xresources

emacs*useXIM: false

The hanging doesn't occur again. But I cannot input with fcitx as well, since fcitx seems to use xim?
