Reading compressed IMG floating point rasters broken

Description 

frmts/hfa/hfaband.cpp line 757. Should copy nDataValue into the array rather
than cast. Should be something like the following:

        else if( nDataType == EPT_f32 )
        {
            int		i;
            float fDataValue;

            memcpy( &fDataValue, &nDataValue, 4);
            for( i = 0; i < nRepeatCount; i++ )
            {
                ((float *) pabyDest)[nPixelsOutput++] = fDataValue;
            }
        }

Change applied.  Would you happen to have a smallish example file that
demonstrates the problem I could test with?
