>Description:
The locate.updatedb script fails to generate the locate.database file when trying to execute locate.code with a bigram string beginning with a dash ('-').
>How-To-Repeat:
It will be hard to recreate a data set that will generate a bigram string beginning with a dash ('-') without providing the full file listing from my system. I don't really want to do that for privacy reasons. But the bigram string from my system was:

>Fix:

Apply the following patch to locate.updatedb:

--- /usr/libexec/locate.updatedb.orig   2023-01-19 23:23:12.655056582 -0500

        echo 'locate: updatedb failed' >&2
        exit 1
 else
-       $LIBDIR/locate.code "$BIGRAMS" <"$FILELIST" >"$FCODES"
+       $LIBDIR/locate.code -- "$BIGRAMS" <"$FILELIST" >"$FCODES"
        chmod 644 "$FCODES"
 fi

This patch is against:
head -4 /usr/libexec/locate.updatedb
#!/bin/sh
#
#       $NetBSD: updatedb.sh,v 1.15 2014/08/04 21:56:30 apb Exp $

But should work for the HEAD version (1.17) with adjustment for line  numbers.
