Yes, as rickg22 says, I've overwritten my RC2 with an SVN build, but kept the directory. And I think this may be the causes of the problem, for after I made a fresh new svn directory and downloaded the sources, I got a successful build and the result program not crash. Inaddition to this, I changed the zip cmd in update srcipt from 7-zip to Info-zip 2.32.
I hope these information will help those who encountered the same problem s as me.
