Great catch @clalancette! The hashid.c file is generated from some files in ddsrt now but I forgot to remove src/hashid.c. It's a surprise to me older versions let it slip. I'm happy to merge the PR, but before I do, may I request you sign the ECA? There's no need for a "Signed-off-by" footer anymore, but the signing the ECA is still mandatory even for small obvious fixes like this one. If you click the Details link next to the failed check, it should take you to the right form. Thanks.

Thanks, I'm running it through internally. I'll "revalidate" once I've signed the agreement.

Closing this in favor of #737.
