Public bug reported:

The version of hideif.elc shipped with emacs 24.5.1 is broken.  This
leads to errors when parsing certain C header files with semantic.

Example header which produces this problem:

 /* #undef __INT_MAX__ */
 /* #define __INT_MAX__ 0x7fffffff */

 #if __INT_MAX__ == 12345678
 #endif

 (parsing this header leads to errors such as Wrong type argument:
number-or-marker-p, \"0x7fffffff\"). See also
http://sourceforge.net/p/cedet/mailman/message/34367892/

The problem goes away when replacing the current hideif.elc (at
/usr/share/emacs/24.5/lisp/progmodes/hideif.elc) with a file byte-
compiled from the source from emacs master, e.g. the version at revision
d1521c64 from
https://github.com/typester/emacs/blob/d1521c64e34debe1618313fbed0e7354b28bf0ae/lisp/progmodes/hideif.el

In other words, the problem is already fixed in newer versions of emacs,
but since the solution is quite simple, maybe the ubuntu package for
emacs 24.5.1 could be patched?
