[DTrace-devel] [PATCH 5/5] print: initialize dv_last_depth when print()ing arrays

[Nick Alcock]

Much like ++ / -- earlier, print()ing arrays initializes a second copy of a
relevant structure (in this case, dt_visit_arg) but fails to initialize all
its members, leading to (theoretical) wrong-looking output as nonsense off
the stack is interpreted as a nesting depth.
