Well, it's defined the next level up on the stack, and it's still garbage. The
way I read gist.c and how it's calling gistUserPicksplit at line 1083, it's not
initialized prior that else. So, FunctionCall2 in gistutil.c is supposed to
fill it out? Presumably a function supplied by PGSphere in this case?
