Homebrew-core: gdb 7.12.1 update fails with '--with-guile' since guile-2.2.2 update

[robohack]

Please always follow these steps:

• [x] Confirmed this is a problem with only one, specific formula and not Homebrew/brew? If it's a general Homebrew/brew problem please file this issue at https://github.com/Homebrew/brew/issues/new
• [x] Ran brew update and retried your prior step?
• [x] Ran brew doctor, fixed as many issues as possible and retried your prior step?
• [ ] Ran brew gist-logs <formula> (where <formula> is the name of the formula that failed) and included the output link?
• [ ] If brew gist-logs didn't work: ran brew config and brew doctor and included their output with your issue?

The gdb 7.12.1 update fails when recompiling from source and using with '--with-guile' since the guile-2.2.2 update.

Please report this to upstream.

[robohack]

FYI, I won't be able to do that.

[ilovezfs]

OK, I'll close this for now.

[robohack]

The correct solution would be to remove the feature that cannot possibly work.

[MikeMcQuaid]

@robohack If you're not willing to report issues to upstream when they are upstream issues: please do not report issues to Homebrew, thanks.

[ilovezfs]

@robohack this should be fixed now (by #12829 which I just merged) if you brew update
