#11025: exec_file raises error if run in loop

     Type:  Bugs                     |     Status:  new
Milestone:  To Be Determined         |  Component:  Python
  Version:  Boost 1.55.0             |   Severity:  Problem
 Keywords:  file loop python script  |
-------------------------------------+---------------------
 We tried to run a soak test of our code which uses boost::python, but
 found that after 509 runs the file could not be read. Found the cause to
 be boost::python not closing the FILE after an fopen. Line 91 in exec.cpp.

 Adding fclose(fs) after PyRun_File seemed to fix the problem.

 You can reproduce the problem with the following code:

 {{{
 int _tmain(int argc, _TCHAR* argv[])
 {
             int count = 0;
             Py_Initialize();
             while (true)
             {
                         auto strScriptFile =
 "D:\\Scrap\\ConsoleApplication2\\SampleCustomMacroOne.py";

                         object main_module = import("__main__");
                         dict globalDict =
 extract<dict>(main_module.attr("__dict__"));
                         exec_file(strScriptFile, globalDict);

                         std::cout << count << endl;
                         count++;
             }

             return 0;
 }

 }}}
