The '-ffloat-store' option works! Thank you.

However that gave me some quenstions;

    Is that feature or bug?

    There is many floating point operations of course.
    Why the only one specific resion make problem?

    That is not set when optimize.
    So, what's the disadvantage and
    why the 'fortran' with many floating point operation
    dosn't take it when optimize?

    Why x86 need that option but x86_64 or PPC do not need?
