We've got this test failure here on the Debian package. It appears randomly (however, oftenly), so it's hard to tell what triggers this, nor how to successfully reproduce it.

Anyway, any hint on this or a fix would be very welcome.

Bắt đầu với testing/test_gateway.py::TestPopenGateway::test_waitclose_on_remote_killed và tái hiện lỗi nhiều lần, sử dụng báo cáo Debian được liên kết và các build log để làm ngữ cảnh. Được xem là hoàn tất khi trường hợp remote-killed hoạt động nhất quán, phát sinh EOFError từ waitclose và IOError từ channel.send mà không xảy ra segmentation fault.
