Please note we will close your issue without comment if you delete, do not read or do not fill out the issue checklist below and provide ALL the requested information. If you repeatedly fail to use the issue template, we will block you from ever submitting issues to Homebrew again.

Please always follow these steps:

• Confirmed this is a problem with brew installing one, specific Homebrew/homebrew-core formula (not cask or tap) and not every time you run brew? If it's a general brew problem please file this issue at https://github.com/Homebrew/brew/issues/new. If it's a brew cask problem please file this issue at https://github.com/Homebrew/caskroom/homebrew-cask/new. If it's a tap (e.g. Homebrew/homebrew-php) problem please file this issue at the tap.

• Ran brew gist-logs <formula> (where <formula> is the name of the formula that failed) and included the output link?

$ brew gist-logs rcs
https://gist.github.com/db926459d7f197fd78270d64dfa93dd9

• If brew gist-logs didn't work: ran brew config and brew doctor and included their output with your issue?

To help us debug your issue please explain:

• What you were trying to do (and why)

Trying to run rcsdiff against a file. That fails. rcsdiff fails with zero args in the same way. Other rcs-based functions can be made to fail similarly.

• What happened (include command output)

% rcsdiff ts
Illegal instruction: 4

• What you expected to happen

I expected the programme to function correctly, not field an illegal instruction trap.

• Step-by-step reproduction instructions (by running brew install commands)

It appears that there is some change in the underlying system library implementation.

This is now fixed if you brew update.
