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(main_module.attr(""__dict__"")); exec_file(strScriptFile, globalDict); std::cout << count << endl; count++; } return 0; } }}}" Bugs closed To Be Determined python USE GITHUB Boost 1.55.0 Problem duplicate file loop python script
