Unknown variable eq3 / eq6

[Lucas Tesson]

Hey, while working on the validation framework discussed in the SIG, I copy-pasted enough code to generate vectors, and discovered some variables (eq3 and eq6) are unknown but used. As this does not panic in logs, I guess they are shared across functions, but can't confirm.

EQs are declared here.

Then EQ3/EQ6 are used with another name in multiple places (e.g. here and there).
