thank you.

I've built vanilla freetype2 on latest CVS, and
I could not reproduce 1.jpg. My result is same
with 2.jpg. Please describe detail of your ftview.

By commenting-out following 2 macros:

/* #define TT_CONFIG_OPTION_BYTECODE_INTERPRETER */
/* #define TT_CONFIG_OPTION_UNPATENTED_HINTING */

I disabled bytecode interpreter, but the result is
same with 1.jpg. I'm not sure whether your trouble
is related with hinting.

My analysis of the font file is following, no cmap
but not broken.
