Crash in byte compiling leim/quail/quick-cns.el (WXP using MSVC 2003)

Crash in byte compiling leim/quail/quick-cns.el (WXP using MSVC 2003)

[dhruva]

Hello,
 I am trying to build emacs from HEAD on WXP using MSVC VC 2003 compiler. I get a crash. The same works if built using GCC (MinGW) tool set.
The following command causes the crash (executed from 'nt' folder):
"E:\sandbox\build\emacs\leim/../src/obj-spd/i386/emacs.exe" -batch --no-init-file --no-site-file --multibyte  -l E:/sandbox/build/emacs/leim/../lisp/international/quail  -f batch-byte-compile ../leim/quail/quick-cns.el

Where does it crash?  Can you show a backtrace?

In file coding.c:
attrs = CODING_ID_ATTRS (coding->id);

where:
coding->id is 159

So what, `coding' is an invalid pointer, and thus dereferencing it
bombs?  Or does something else crash inside the CODING_ID_ATTRS macro
(defined on coding.h)?

Is this an optimized build or not?  If it's optimized, can you try
with unoptimized one?
