"gzip --version" gives "Abort trap: 6" in macOS

I found that doing gzip --version in the terminal on my Mac just gives output Abort trap: 6. I came across this because it appears to cause another program to exit when it searches for the installed gzip version. Is there a way to fix gzip? I looked for information about how to reinstall it, thinking that might just fix it, but couldn't find out how to.
