"op->_ob_prev->_ob_next" comes from _Py_ForgetReference() compiled in pydebug mode and it should ends with "UNREF invalid object" but it looks like _PyObject_Dump(op->_ob_next->_ob_prev); crashed. Anyway, something gone wrong here.

It still happens on the same builder, occasionally. http://www.python.org/dev/buildbot/builders/sparc%20Debian%203.1/builds/24

I did not see this failure since one year. flox saw it 7 months ago. I close this issue because I think that it is fixed. Reopen it if the issue was not fixed.
