Homebrew-core: `brew install valgrind` fails but new version is available

[timotheecour]

Please always follow these steps:

• [x] 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/caskroom/homebrew-cask/issues/new. If it's a tap (e.g. Homebrew/homebrew-php) problem please file this issue at the tap.
• [x] Ran brew update and retried your prior step?
• [x] Ran brew doctor, fixed all issues and retried your prior step?
• [x] Ran brew gist-logs <formula> (where <formula> is the name of the formula that failed) and included the output link?
• [x] If brew gist-logs didn't work: ran brew config and brew doctor and included their output with your issue?

brew install valgrind
valgrind: This formula either does not compile or function as expected on macOS
versions newer than Sierra due to an upstream incompatibility.
Error: An unsatisfied requirement failed this build.

brew gist-logs valgrind
Error: No logs.

brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  numpy
  opencv_dbg

Warning: Your Homebrew's prefix is not /usr/local.
You can install Homebrew anywhere you want but some bottles (binary packages)
can only be used with a /usr/local prefix and some formulae (packages)
may not build correctly with a non-/usr/local prefix.

Warning: Some directories in your path end in a slash.
Directories in your path should not end in a slash. This can break other
doctor checks. The following directories should be edited:
  /Users/timothee/usr/local/bin/

workaround: brew install --HEAD valgrind
not sure why https://github.com/Homebrew/homebrew-core/issues/18998 was closed; why not keep it open until brew install valgrind works?

EDIT:

maybe sourceware.org is flaky? takes ~120 seconds; sometimes works, sometimes times out; maybe we can increase timeout in brew formula? how?
after trying a few times it works. But we should still keep bug open until
brew install valgrind works without --HEAD

We don't keep issues or PRs open as placeholders.

There is also an http mirror for the repository set up at repo.or.cz. You can use it if you are behind a firewall and cannot tunnel through with socat. To clone from this mirror, do this:

git clone http://repo.or.cz/valgrind.git

Same issue here with brew install --HEAD valgrind

[joshuakim314]

having same issue :(

[inumanag]

Workaround: do brew edit valgrind and replace https://sourceware.org/git/valgrind.git with git://sourceware.org/git/valgrind.git in head section of the formula.
