[Python-Dev] SystemErrors in generator (just happened in 2.5) (original) (raw)

There were some SystemErrors on one of the Windows build slaves. Does anyone have any ideas what might be the cause? I looked through about 5 previous logs on the same slave and didn't see the same problem. I haven't seen this myself and I don't know if it's WIndows specific. I don't know if this has happened on the trunk or just 2.5.

For the full log see: http://python.org/dev/buildbot/2.5/x86%20XP%202.5/builds/197/step-test/0
