This silences the spurious -Wclobbered warning and also fixes a related piece of undefined behaviour that never got warned about because ctx never got reused for anything else.

We will never, ever disable warnings beyond the scope of one function, but this is okay. Failed build was Travis for some reason never even starting the mono builds.
