New submission from STINNER Victor: Using pyfailmalloc, I'm able to reproduce the crash seen on a buildbot.
Attached patch fixes two bugs in error handlers. http://buildbot.python.org/all/builders/AMD64%20OpenIndiana%203.x/builds/8557/steps/test/logs/stdio [191/390] test_urllib2net Fatal Python error:
