        gcc: 2.8.1

        I use ld with option --oformat coff-go32 to generate COFF images.

        unsigned char* pVideo=(unsigned char*)0x000b8000;
        unsigned char j='Z';

        However, the above codes don't work at all, i.e., the pVideo
        does not point to 0x000b8000.

        If modify the above codes to the following:

        unsigned char* pVideo;
        unsigned char j;

        pVideo=(unsigned char*)0x000b8000;
        j='A';

        Now, pVideo does point to 0x000b8000.

        Is there anything wrong with COFF images generated by ld?
