Re: Regression in current trunk?

[Angelo Graziosi]

Well, with a binary search, here there are a few results:


cvs up -dP -D "20080829 09:50" builds and works fine with big file

cvs up -dP -D "20080829 09:55" fails to build

cvs up -dP -D "20080829 10:00" builds and shows the regression discussed
                               here


These changes seem the cause:

2008-08-29 Kenichi Handa <address@hidden>

       These changes are to re-implement the automatic composition so
       that it doesn't use text properties.

       * Makefile.in (ftfont.o): Depend on composite.h.
       (composite.o): Depend dispextern.h, font.h, frame, and window.h.

       * character.h (Vunicode_category_table): Extern it.
[...]


Attached the source differences.


Cheers,
   Angelo.
