Thanks, but this is not a bug.
To search for a pattern that starts with "-", use grep's -e option, e.g.,

  grep -e -/ example.txt

Also, you're using grep-2.20, which is more than 8 years old.
The latest is grep-3.8.

Hello,

When searching for a pattern that includes "-/", the pattern is interpreted as option:

[dsg@db01]# grep "-" example.txt
--/--
[dsg@db01]# grep "/" example.txt
--/--
[dsg@db01]# grep "-/" example.txt
grep: invalid option -- '/'
Usage: grep [OPTION]... PATTERN [FILE]...
Try 'grep --help' for more information.
[dsg@db01]# grep --version
