I am having a problem with the WM_CHAR message. Maruzzi and Petzold
document message crackers for the WM_CHAR message. When I try to use
them under Borland C++ 1.01 for OS/2, the code generates an access
violation. The normal SHORT1FROMMP() macro works as a drop in
replacement.

What am I doing wrong (if anything) 


// This code bombs...

case WM_CHAR:
    if ( CHARMSG( mp1 )->fs & KC_CHAR & ~KC_KEYUP )
    {
        cp->PutChar( CHARMSG( mp2 )->chr ) ;
    }
    break ;

// This code works fine...

case WM_CHAR:
    if ( SHORT1FROMMP( mp1 ) & KC_CHAR & ~KC_KEYUP )
    {
        char ch = SHORT1FROMMP( mp2 ) ;
        cp->PutChar(&ch) ;
    }
    break ;
