            Bug ID: 28806
           Summary: Clang AST generates invalid line number with
                    CXXMethodDecl and CallExpr
           Product: clang
           Version: 3.7
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org

I use CLANG in a project that scans projects and creates an AST.  I look for
patterns in the AST an flag them for the user.  The flagging uses a bookmark at
a line number.  This line number is extracted from the CLANG AST.  I have
noticed that on "CallExpr" and "CXXMethodDecl", CLANG will indicate a line
number in another reference file.  The line numbers sometimes stay within that
reference file, providing invalid line numbers for the file I want to flag. 
The line numbers in the AST eventually return to the original file I am
scanning, but not before picking up invalid line numbers.  I have include a
Visual Studio project that produces this problem, a sample AST output, and a
document explaining where this AST deviates and where in returns.  The document
also explains that with the "CXXMethodDecl" in an include file, the problem is
much worse.
