It seems that the memmapped area is an invalid address.  I have no
idea why this problem happens.

I've tested 026 for more than ten hours on several machines, but I
couldn't reproduce this problem.  Doesn't it happen with the current
master branch?  If it happens, I'd like to apply the series to move
forward.  I'll give a fix after I reproduce this crash problem.

Thanks,
