When I build it with gcc-3.3.3, the problem disappears.  I guess the older
gcc's XMM macros were buggy.

Thanks for the suggestion.

Actually, the crash occurred with even very simple options.

I'm now encoding the very same file which caused segfaults in the
gcc-3.2.3-built binary.

I would probably put a note (or modify the build script to detect/warn the
user) about gcc-3.2 and --enable-sse.  I suspect if we lookup the gcc
bugbase, we'll see some changes made to the SSE intrinsics.
