Hi,
I finally set up a linux machine (RedHat 8.0), and was able to reproduced
the bug.

I believe it is a db(3)'s bug that has been hidden. But why the trouble
occurs in GNU/Linux, but doesn't occur in FreeBSD?
Examining the difference of two system, it was found that
the default page size were different each other.
The page size is 4096 in GNU/Linux and is 8192 in FreeBSD.

Would you please reexecute gtags with the following modification?
It works in my environment.

        if (flags & DBOP_DUP)
                info.flags |= R_DUP;
+       info.psize = 8192;
        /*
         * accept user's request but needs 0.5MB at least.
         */

If it works in your environment too, how about seeing the appearance
after applying above modification?
Of course, it is not the solution of the problem. But since we have
not noticed the trouble for a long time up to now, it is worthy enough
to put off the problem.
I will fix the bug when there is time a little more.
