Description:
------------
The entire MBREGEX.C object appears to be written with "pointer address
math" using "int" variables.
Whereas we all know that with the invent of i586/i686 systems the int
veriable is nicely 32 bit, in a 64 bit environment, the pointers and
the uint/int objects become completely incompatible.
(Am I crazy here?)...or completely stupid?
Anyway...lot's of "pointer errors" in mbstring/mbregex. It appears
that this module is totally unusable in a 64-bit environment.
To FIX, I did the following
mbstring/mbregex/mbregex.h
#define MINT long
#define MLONG long
The changed all "int"'s to "MINT"
and changed all "long"'s to "MLONG"
with a nice search and replace.
Compiled with no compiler warnings (retesting make clean/make as we
speak).
It actually appears that the entire mbstring object must be completely
re-written. SOOOO much pointer math using int's and so many "cast from
pointer to integer of different size" errors.
any chance of getting 4.3.9 or 4.3.10 compilable for 64-bit?
I have a lot of work left to fix all the mbstring files that wont
compile correctly...errrrg!!!
PLEASE someone tell me I can ignore these because the pointer math
works even when the compiler complains!!
Reproduce code:
---------------
compile mbstring/mbregex.c
Expected result:
----------------
no compiler warnings about bad pointers
Actual result:
--------------
compiler warnings about bad pointers
------------------------------------------------------------------------
