Yes, that is the standard goto tool for memory leaks.

This is the history of the python bindings: https://github.com/linux-audit/audit-userspace/commits/master/bindings/ python/auparse_python.c > As the next versions of audit doesn't have this issue, You mean 2.3.3? > I'm sure that you can find some patch which deals with this issue. Take a look through the history. One of them does it. I think one might even mention memory leak. -Steve -- Linux-audit mailing list Linux-audit@redhat.com https://listman.redhat.com/mailman/listinfo/linux-audit
