            Bug ID: 20321
           Summary: CLANG_ENABLE_REWRITER=0 makes crash report unavailable
                    (preprocessed source is not generated)
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: geek4civic at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

With ENABLE_REWRITER=ENABLE_STATICANAYZER=ENABLE_ARCMT=0,
clang/test/Driver/crash-report.c fails.

  clang-3.5: note: diagnostic msg: Error generating preprocessed source(s).

When creating preprocessed source in crash reported,
clang -E is invoked with -frewrite-includes. (Driver/Tools.cpp:4140)
Without ENABLE_REWRITER, clang -frewrite-includes fails.
