Two days ago, a patch was sent to Guix updating libx11 to a newer
version in order to fix CVE-2020-14344. This causes a segmentation
fault in Emacs when trying to start an X window. After invoking GDB, I
found the offending line to be:
/* Determine XIC style */
xic_style = best_xim_style (FRAME_X_XIM_STYLES (f));
For some reason, FRAME_X_XIM_STYLES (f) returns NULL here and
best_xim_style fails when ARRAYELTS is called on it. I've attached a
patch, that checks for this case.
