>Description:
        Searching for a long string is broken on LP64 architectures (at least
        sparc64 and amd64) in nvi.  Tested on sparc64/4.99.72, sparc64/5.0RC2
        and amd64/current.  The same tests succeed on i386.  (Thanks to ober@
>How-To-Repeat:
        Edit a new file with vi.
        Enter a line containing:
          g_thread_functions_for_glib_use
        Search for the whole string.  See it display "Pattern not found".
        Note, that searching without the final 'e' will succeed.
        Note, also, that amd64 fails for the string:
          abcdabcdabcdabcdabcdabcdabcdabcd
        (it advances the cursor one char each time 'n' is pressed)
>Fix:
        Unknown.
