Category: Python Interpreter Core Group: Python 2.5 Status: Open Resolution: None Priority: 7 Private: No Submitted By: Mike Klaas (mklaas) Assigned to: Nobody/Anonymous (nobody) Summary: Segfault provoked by generators and exceptions Initial Comment: A reproducible segfault when using heavily-nested generators and exceptions. Unfortunately, I haven't yet been able to provoke this behaviour with a standalone python2.5 script. There are, however, no third-party c extensions running in the process so I'm fairly confident that it is a problem in the core. The gist of the code is a series of nested generators which leave scope when an exception is raised. This exception is caught and re-raised in an outer loop. The old exception was holding on to the frame which was keeping the generators alive, and the sequence of generator destruction and new finalization caused the segfault. -- Comment By: Eric Noyau (eric_noyau) Date: 2006-11-27 18:07 Message: Logged In: YES user_id=1388768 Originator: NO We are experiencing the same segfault in our application, reliably.

Neal, note that it's the /Windows/ malloc that fills freed memory with "dangerous bytes" in a debug build -- this really has nothing to do with that it's a debug build of /Python/ apart from that on Windows a debug build of Python also links in the debug version of Microsoft's malloc. The valgrind report is pointing at the same thing. Whether this leads to a crash is purely an accident of when and how the system malloc happens to reuse the freed memory. -- Comment By: Neal Norwitz (nnorwitz) Date: 2006-10-28 05:56 Message: Logged In: YES user_id=33168 Mike, what platform are you having the problem on?
