Its an unitialised pointer which is then used as the target of a
sprintf.  Whether it works depends on how your system intialises (or
not) automatic variables, and possibly what was on the stack just
before the function was called.

The problem is with the exit_prog() function in exit.c .
The fix is to change the
  char * msg
to something like
  char msg[STRING]

I gave a patch to Syd earlier in the week, I assume he will issue an
official fix soon.
