Hi!

I get this error when building an app using ring-0.17.8

error[E0080]: evaluation of constant value failed

  = note: this error originates in the macro `assert` (in Nightly builds, run with -Z macro-backtrace for more info)

For more information about this error, try `rustc --explain E0080`.
error: could not compile `ring` (lib) due to 1 previous error

I tried to find info using the three issue links in the code, but I don't have enough experience with rust, to be honest, I'm just packaging an application. It seems to me that the problem is with the assert call itself, so perhaps this is actually a bug?

Removing the check will make the code build.

Do you need more information, just specify what is needed. Build log attached.
