yes, but it's not due to the amd64 cpu, it might be a bug of mesa or
some other packages, for if i build and run the examples on debian
testing on the same amd64 machine, which is with mesa-7.0.3, the
window can resize normally, so it might be the bug of mesa-7.4, but my
debug technology is so poor, i cannot get any information about the
crash by gdb, only "segmentation fault".
