Thanks for the report.
First of all, please teach your bot to cut up things a bit. ~13k lines is something not expected here, really!

Test does the overflow check with 1024 as a parameter and comments deliberately tells about limitation. What it should do instead is to use the actual GPIO number from the kernel configuration.
