>Description:
I've got devel/glib20 built WITH_COLLATION_FIX=yes . The last commit to devel/glib20/Makefile adds a __STDC_ISO_10646__ definition to configure arguments for that option. The problem is pidgin (net-im/pidgin) constantly crashes if all conditions below are met:
a) glib20 built WITH_COLLATION_FIX=yes
b) glib20 built after that commit (so with __STDC_ISO_10646__ definition)
c) pidgin is started with uk_UA.KOI8-U locale

, but works well when any of three requirements above is lifted, e.g. if i reset locale to C, or if the commit is reverted (as it was before) it works well.
 According to the `pidgin -d` log the crash occurs somewhere during constructing the buddy list (either read from the local configuration in ~/.purple or after an account added and the server contact list is read when started from scratch with no ~/.purple existing).
 Also, the possible significant condition is that the buddylist contains non-latin group names (while buddy names are all latin)
>How-To-Repeat:

>Fix:
Revert the __STDC_ISO_10646__ definition commit
or
unset devel/glib20 WITH_COLLATION_FIX=yes option
or
run an application (pidgin) with C locale
