11024	exec_file raises error if run in loop	edward.terhaar@…	Ralf W. Grosse-Kunstleve	"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;
}
