Fixed in 7.1.1 thanks to @avocadomaster for the fix, and thanks for the report @jcloutz-radix.

I'll investigate how to catch this in builds/CI.

[evanshortiss]

@avocadomaster @Lioness100 @jcloutz-radix lib files are now checked in builds (commit), so these errors will be caught in the future.

Awesome, thank you @evanshortiss
