The attached patch should fix the valgrind error you pointed out.  Strangely
enough I have been unable to reproduce the crash, even while running the same
binary you compiled yourself.  The conditional jump depending on uninitialized
memory doesn't explain the problem, it seems fully harmless.  What platform are
you running this on?  And what exactly is the nature of the crash you're
seeing?  (segfault?)
