Here, valgrind is complaining about some uninitialized fields, and in
the gdb stack trace, the program was copying data based on one of
those same fields having a nonzero value. If the uninitialized
length field was nonzero, and the data pointer was null or garbage,
the copy would fail. So, it looks like valgrind did dig up a little
more information on this bug.
Thanks, I'll see if I can track down what's going on.
