[luatex] Segmentation fault on LuaTeX

[Hironori Kitagawa]

Hello,

I found that the following source (b.tex, say):

 > %#!luatex
 > \newcount\X
 >
 > \X=1
 > \loop A%
 >   \advance\X by 1
 >   \ifnum \X < 10000
 > \repeat
 >
 > \end

causes a segmentation fault on LuaTeX.

$ luatex b
This is LuaTeX, Version beta-0.71.0-2012082121 (rev 4465)
  restricted \write18 enabled.
(./b.texSegmentation fault

If I the number on the line 7 reduced from 10000 to 1000,
this segmentation fault disappeared.

Does anyone know the cause of this behavior?
