Material Compile Error [SM5]

There is an material compile error when using a TexCoord node shared between two Texture samples.

The user provided a number of ways to work around the issue, but this issue becomes more problematic when using a more complex material and attempting to reduce instruction count by combining texture coordinates.

Error [SM5] Material.usf(1564,118): error X3004: undeclared identifier 'Local0'

Error [SM5] Material.usf(1564,53): error X3013: 'Texture2DSample': function does not take 3 parameters

Regression?
Yes, this error does not occur in 4.11.2 with the same material set up shown in the attached image.

1. Open attached project.
2. Open the M_Compile Error

Outcome
There is a material compile error when sharing a TexCoord between two TextureSamples

Expected
No shader compiler errors
