Description:
Fvwm crashes in free() in libc couple of times per day. Crashes
are different, and call path can involve different libraries,
but the problem is always in free().
Here is an example:

The above crash happened when I closed a tab in Firefox and window
title changed.
Repeat-By:
I am not sure, but the problem seems to appear after I have
switched my locale from ru_RU.KOI8-R to ru_RU.UTF-8.
Fix:
Not known.
