db DSP_V[3].SRCN

This produces error: (Estruct_not_found): Struct 'DSP_V' wasn't found. [db DSP_V[3].SRCN]. The first three db instructions compile; removing the fourth db causes Asar to "correctly" produce 00 10 01.

The cause is that struct field labels are saved with namespace, but struct labels are not. Since they are resolved together when accessing a struct element's field, these fields are entirely inaccessible.
