Hello, Working with Boost 1.58, I am using Boost.Python to interpret python code. eval() and exec() are working as expected, however exec_file results on a double delete upon finishing reading the script. This can be observed in the following minimal: #include int main() { Py_Initialize(); boost::python::exec_file("foo.py"); } where foo.py contains a single line: print "hello" hello is printed on the screen - i.e. the script is completed before the crash. Valgrind also finds a number of invalid reads in the exec_file line before an invalid free/delete. Is there something I'm missing in exec_file usage, or do you think there might be a mismatch of dependencies? (using boost and python both from my package manager). Thank you, Albert
