A build that CANNOT_DUMP should load loadup.el at startup. Does this
build do it?
When loadup.el is loaded it loads charprop.el. Does thi happen with
this build?
When charprop.el loads, it runs this code:
(define-char-code-property 'bidi-class "uni-bidi.el"
"Unicode bidi class.
Property value is one of the following symbols:
L, LRE, LRO, LRI, R, AL, RLE, RLO, RLI, FSI, PDF, PDI,
EN, ES, ET, AN, CS, NSM, BN, B, S, WS, ON")
When this code runs, it should load uni-bidi.el, which defines the
char-table accessed in the above snippet.
What I think happens in your case is that bidi_initialize is called
_before_ all of the above happens, probably because Emacs wants to
display some message in the echo area during loading loadup.el, or
maybe even earlier. If so, the solution should be to disable bidi
until loadup is done, and turn it on afterwards. One way of disabling
bidi is to (setq-default bidi-display-reordering nil) (or its C
equivalent) at the beginning of 'main', or maybe at the beginning of
loadup.el (if you can detect CANNOT_DUMP from Lisp). Then turn it
back on when loadup.el finishes by setting bidi-display-reordering to
t.
Can you try that?
