Could you please share the corresponding OBJ here [also the MTL if there is one]
Otherwise we cannot reproduce this issue...

Marking as incomplete until we have that...

Can confirm the vert mismatch. Can also confirm this is coming in without errors in 2.79...
Will confirm for now, @Bastien Montagne (mont29) might know right away? (feel free to throw back at me and I will investigate more...)
[This might not be a bug but a broken OBJ though...]

But for all kind objects in OBJ file format be like this cant acces in Blender 2.8 , i am working during many months on Blender 2.8 only the way i import OBJ in Blender 2.8 by first i import to Blender 2.79 and than make Copy to Clipboard and Paste in Blender 2.8 or i export from Blender 2.79 OBJ for can import in Blender 2.8 or i import from Netfabb or Maya Obj to blender 2.8 for can work in .
Only from Rhino 3d Cant access import to Blender 2.8 , by the way i am using Rhino V5 , i dont know if its should use Rhino V6 for OBJ can import to Blender 2.8 .

OK, so not related in the end, this is a parsing issue, still trying to understand what happens exactly here.
