This is because the > {{StartSlave}} helper takes raw pointer arguments, which may be > stack-allocated. > In case of an assert failure, the test immediately exits (destroying stack > allocated objects) and proceeds onto test cleanup. The test cleanup may > dereference some of these destroyed objects, leading to a test crash like: > {code} > [18:27:36][Step 8/8] F0204 18:27:35.981302 23085 logging.cpp:64] RAW: Pure > virtual method called > [18:27:36][Step 8/8] @ 0x7f7077055e1c google::LogMessage::Fail() > [18:27:36][Step 8/8] @ 0x7f707705ba6f google::RawLog__() > [18:27:36][Step 8/8] @ 0x7f70760f76c9 __cxa_pure_virtual > [18:27:36][Step 8/8] @ 0xa9423c > mesos::internal::tests::Cluster::Slaves::shutdown() > [18:27:36][Step 8/8] @ 0x1074e45 > mesos::internal::tests::MesosTest::ShutdownSlaves() > [18:27:36][Step 8/8] @ 0x1074de4 > mesos::internal::tests::MesosTest::Shutdown() > [18:27:36][Step 8/8] @ 0x1070ec7 > mesos::internal::tests::MesosTest::TearDown() > {code} > The {{StartSlave}} helper should take {{shared_ptr}} arguments instead. > This also means that we can remove the {{Shutdown}} helper from most of these > tests. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
