I'm having trouble installing Valgrind on a newly updated Mac OS X Catalina.
When I try get this error
brew install valgrind
valgrind: This formula either does not compile or function as expected on macOS
versions newer than High Sierra due to an upstream incompatibility.
Error: An unsatisfied requirement failed this build.
And then after changing the HEAD url to url "git://sourceware.org/git/valgrind.git" ANd trying to install it through
brew install --HEAD valgrind

And neither of them work. Any help is appreciated.
