<pre>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.</pre>
