Dear Maintainer,

At -O2 gcc miscompiles the following snippet of C code

        V2083= ({register object _z=vs_base[0];register object 
*_x=vs_base+1,*_y=(object *)V2048;if (!_y) vs_top=base; else {for(;_x<vs_top;) 
*_y++=*_x++;if (_x>vs_top) _y--;vs_top=_y;}_z;});

Hi Camm, please could you report that upstream?  Also maybe testing that 
with trunk (gcc-16/gcc-snapshot?

Thanks, Matthias
