This is a duplicate of rdar://21374780 - Example is attached in the original radar. Summary: When using Xcode 7 new address sanitizer feature, xcode runs ditto command with the wrong path for libclang_rt.asan_iossim_dynamic.dylib file. The path the xcode provides ditto command is relative to the CC environment variable, which is wrong because the file is located under the Toolchain and not relative to the custom CC command which can be anywhere. Steps to Reproduce: 1. Create a project with Xcode 7 2. Create a link to clang (e.g. /tmp/cusom_clang) 3. Set the CC user defined variable to point to the custom clang path (CC=/tmp/cusom_clang) 4. Enable address sanitizer in the schema 5. Build the project Expected Results: Build successful Actual Results: Build fail with the following error: Ditto /Users/sergey/Library/Developer/Xcode/DerivedData/SanitizerAndCC-cpkpilypgjjrbveuebtzugjkcszm/Build/Products/Debug-iphonesimulator/SanitizerAndCC.app/Frameworks/libclang_rt.asan_iossim_dynamic.dylib /tmp/lib/clang/7.0.0/lib/darwin/libclang_rt.asan_iossim_dynamic.dylib cd /tmp/SanitizerAndCC export PATH="/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/Applications/Xcode-beta.app/Contents/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /usr/bin/ditto -rsrc /tmp/lib/clang/7.0.0/lib/darwin/libclang_rt.asan_iossim_dynamic.dylib /Users/sergey/Library/Developer/Xcode/DerivedData/SanitizerAndCC-cpkpilypgjjrbveuebtzugjkcszm/Build/Products/Debug-iphonesimulator/SanitizerAndCC.app/Frameworks/libclang_rt.asan_iossim_dynamic.dylib ditto: can't get real path for source '/tmp/lib/clang/7.0.0/lib/darwin/libclang_rt.asan_iossim_dynamic.dylib' Command /usr/bin/ditto failed with exit code 1
