If you don't want to read about the details of using Valgrind, there are still two things you must do to suppress the warnings. First, you must use a suppressions file. One is supplied in -Misc/valgrind-python.supp. Second, you must do one of the following: - - * Uncomment Py_USING_MEMORY_DEBUGGER in Objects/obmalloc.c, - then rebuild Python - * Uncomment the lines in Misc/valgrind-python.supp that - suppress the warnings for PyObject_Free and PyObject_Realloc +Misc/valgrind-python.supp. Second, you must uncomment the lines in +Misc/valgrind-python.supp that suppress the warnings for PyObject_Free and +PyObject_Realloc. If you want to use Valgrind more effectively and catch even more memory leaks, you will need to configure python --without-pymalloc.
