My guess based on the error message is that the linked project is incorrectly ignoring the build tags.

bypass.go has // +build !appengine,!disableunsafe bypasssafe.go has // +build appengine disableunsafe.

Those build tags allow different compile time behavior for the constants in question.

I'm going to close this as it's not a spew issue, rather one with the withmock package. I've commented there accordingly.

@davecgh No problem. Thanks for taking a look at it.
