Every one of them matches the grep check, and since you enclosed the check in a command substitution, the output of grep (which is the pathname) is *executed* as a command. That's probably where your segfault is happening. Once you remove this completely unnecessary and incorrectly written check, the segfaults from running random shared library files as commands will stop happening.
