            Bug ID: 28118
           Summary: BrainF: double free at exit
           Product: new-bugs
           Version: 3.8
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: vvort at yandex.ru
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

The problem is located in file "examples\BrainF\BrainFDriver.cpp".
Variable std::unique_ptr<Module> Mod gets deleted twice:
1. In main(): with llvm_shutdown() call.
2. After main(): when destructor for unique_ptr is called.
This can be fixed with adding exit(0) call right before return 0 line, but I
hope you will find a better solution.

This program was built in debug mode using Visual Studio 2013 compiler.
