With this patch, CTRL-] in normal mode, or :tag, sometimes fails to work
for me.

For example, go to vim/src/ and open vim there.  Do ":make tags" and ":edit
gui.c".  Place the cursor at gui_attempt_start() at line 110 and press
CTRL-].

Then I got either of them, depending on circumstances:

(1) no response
(2) an error message: E429: File "tags^A^Agui_attempt_start^
Igui.c^I/^gui_attempt_start(void)$/ead_ref" does not exist (N.B. The
substring after $/ often varies).
(3) segfault

Those clearly indicate that memory corruption takes place somewhere
(Therefore, I believe the procedure above is not necessarily useful to
reproduce the issue for everyone).


This should be fixed by PR #1387.

Cheers,
James
