I cannot reproduce this. I tried the same command that triggered the crash for you:
svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm Tried it with 1.8.9-SlikSvn-1.8.9-X64 on Windows 7 (Windows 7 Enterprise, Service Pack 1, build 7601). The checkout succeeded without problems. Does this always crash for you? Anything specific about your system? -- Johan
