------- Comment #4 from pinskia at gcc dot gnu dot org 2007-06-10 02:57 -------
I think this is becuase we are looking into the static array variable's
initializers.
For an example:
static StgWord rY52_closure[] = { (W_)&base_GHCziBase_ZC_static_info,
(W_)&rY50_closure, (W_)&base_GHCziBase_ZMZN_closure, 0x0 };
We add base_GHCziBase_ZC_static_info to the referenced variables but we
actually really don't reference it. This is a compile time hog and a memory
hog at the same time.
