This line:

  argvec[0] = value_struct_elt (arg1, argvec+1, tstr, static_memfuncp, "structure");

should probably pass the *address* of static_memfuncp, to match the
declaration of value_struct_elt in valops.c.  Lint would have told you
this :-)

Here's an example of the bug in action -- sorry it's a bit contrived
and dependent on a particular line-number in a file, but hopefully
you'll get the idea.
