I actually ran it with -Q too, just pasted in the wrong command line.
Sorry.  The same results anyways.  The program aborts whathever the
arguments are (even when there are none), but I got it to run adding
‘-batch’ argument.  Here is what I got from some example sessions:

,----
| g@xi:~/co/GNUEmacs$ src/bootstrap-emacs -Q -batch -eval "(call-interactively 
#'titdic-convert)"
| TIT dictionary file: leim/CXTERM-DIC/CCDOSPY.tit
| Loading macroexp.elc...
| TIT dictionary doesn’t have body part
`----

Here it prompted me for the file name.

,----
| g@xi:~/co/GNUEmacs$ src/bootstrap-emacs -Q -batch -eval "(progn (find-file 
\"leim/CXTERM-DIC/CCDOSPY.tit\") (message \"%d\" (search-forward 
\"\\nBEGIN\")))"
| 1850
`----

Here it does indeed find the ‘\nBEGIN’ string.  The following patch
fixes this error, but IDK if sanely:

diff --git a/lisp/international/titdic-cnv.el b/lisp/international/titdic-cnv.el
index 130bc74..6a593e2 100644
--- a/lisp/international/titdic-cnv.el

          (let ((coding-system-for-read 'raw-text))

And here is what happens now:

Exits 0, file created.  The build also *continues* with this patch
applied.  That ‘set-buffer-multibyte’ line was there since 2002 though
(see commit c7211fed), so maybe some semantics changed recently about
regexps?

Find below a copy of a gdb session.  I do not know much about debugging
C programs, but I'll try and do further debugging in my spare time if
need be.  I guess without -batch it tried to load the GUI which wasn't
properly lined at that time or maybe isn't included in bootstrap-emacs
at all?
