I think this would be nicer:
s = HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, sizeof(*s));
...
v->data = s;

That's mostly my fault for writing it like that in the first place,
but we might as well fix that.

You'll probably want to return E_FAIL here.

If you create a structure for anonymous shaders, you can store that in
a single array. You can then pass a pointer to that structure to
parse_fx10_anonymous_shader(), and handle "anonymous_shader_current"
in parse_fx10_object(). E.g.:

struct d3d10_effect *effect = o->pass->technique->effect;
struct d3d10_effect_anonymous_shader *shader =
&effect->anonymous_shaders[effect->anonymous_shader_current];

hr = parse_fx10_anonymous_shader(effect, o->type, shader);
if (FAILED(hr)) return hr;

++effect->anonymous_shader_current;
o->data = shader;

Note that you should also validate that "anonymous_shader_current" <
"anonymous_shader_count". The count is supposed to be correct, but the
.fx might lie about it, possibly on purpose.
