I can confirm. Doesn't crash when both windows are in Solid mode.

Note: Seems, material causes crash (when remove no crash):

Hum! Attribute dp_wetmap causing crash...

Can't find attribute, on other place, maybe cause of crash...
Note: If you remove text dp_wetmap, no crash at all
Ship Floating - Without Attribute.blend
Thanks

@jakez27 thanks for the report, I have a few questions for you:

Could you reproduce this from scratch in 2.80?
How about a 2.79 file opened in 2.80?
Which version of Blender you used to save the file the last time?

Crash related information:

BLI_assert failed: //source/blender/blenkernel/intern/customdata.c:2074, CustomData_get_layer_index_n(), at 'i + n < data->totlayer'
Full backtrace: P1107

Think that one is for @fclem, at least as a first step? Looks like the mesh from MeshRenderData in extract_vcol_init() does not have the expected data? loop cddata only have three layers, a UV (when orig mesh has none?), a VCol (foam, generated by the Ocean modifier), and the loops themselves…

Crash itself happens just after since CustomData_get_layer_name() finds no valid layer, it returns a NULL name, and extract_vcol_init() does not take care of that case at all.
