[PATCH] D85424: [Analyzer] Crash fix for alpha.cplusplus.IteratorRange

[Balogh, Ádám via Phabricator via cfe-commits]

baloghadamsoftware added a comment.

Unfortunately, I could not create test for it. It is extremely rare that the //Analyzer// creates an `UndefinedVal`. I had the following output:

  1.	<eof> parser at end of file
  2.	While analyzing stack: 
  	#0 Calling llvm::object::BindRebaseSegInfo::BindRebaseSegInfo at line /usr/include/c++/7/bits/unique_ptr.h:821:34
  	#1 Calling std::make_unique at line 4094
  	#2 Calling llvm::object::MachOObjectFile::bindTable at line 4115
  	#3 Calling llvm::object::MachOObjectFile::weakBindTable
  3.	/home/edmbalo/llvm-project/llvm/lib/Object/MachOObjectFile.cpp:4004:28: Error evaluating statement
  4.	/home/edmbalo/llvm-project/llvm/lib/Object/MachOObjectFile.cpp:4004:28: Error evaluating statement

I was analyzing `llvm/lib/Object/MachOObjectFile.cpp` with all the iterator-related checkers enabled.
