is fContext NULL if fCurrVertex is < 0?

Otherwise, which variable is being used uninitialized?

+        bool useColorVerts = !fUseLCDText;
+        set_vertex_attributes(&drawState, useColorVerts);
+
         // setup our sampler state for our text texture/atlas
         SkASSERT(SkIsAlign4(fCurrVertex));
