[Scim-devel] SUPERSCRIPT ZERO (U+2070) Segmentation Fault

[Alexej H. <ale...@xi...>]

Hi,

the following xmodmap(1) configuration causes a segmentation fault in
the EFL project “Terminology” when AltGr+Shift+0 is pressed to enter
SUPERSCRIPT ZERO (U+2070):

  ! Modofier key (AltGr) that can be replaced with another key.
  keycode 108 = Mode_switch Multi_key
  ! Superscript numbers.
  keysym 0 = 0 parenright 0 zerosuperior

This is the gdb(1) output of a crash:

  GNU gdb (Gentoo 7.7.1 p1) 7.7.1
  (gdb) run

I have attached a patch that fixes the problem.
