Your system is ready to brew.

Verification

• My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.
• My issue is not about a failure to build a formula from source.

What were you trying to do (and why)?

use mas to update store applications, through brew bundle

What happened (include all command output)?

store application updates failed:

Installing Infuse
Password:

Installing Infuse has failed!
Installing LastPass for Safari

Installing LastPass for Safari has failed!

then tried directly using mas

loic@MacBook-Pro-de-Loic ~ % sudo mas update
Password:
zsh: illegal hardware instruction  sudo mas update
loic@MacBook-Pro-de-Loic ~ % sudo -i
MacBook-Pro-de-Loic:~ root# mas update
Illegal instruction: 4
MacBook-Pro-de-Loic:~ root# exit

What did you expect to happen?

store app updates to succeed

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

having store apps installed and listed in a Brewfile

brew bundle

or

brew install mas
mas update

[nicerloop]

mas, when installed from original pkg, runs fine.
homebrew build seems faulty.
