James Peach created MESOS-7394:
----------------------------------
Summary: libprocess test failures double-free stack-allocated
processes
Key: MESOS-7394
URL: https://issues.apache.org/jira/browse/MESOS-7394
Project: Mesos
Issue Type: Bug
Reporter: James Peach
Some of the {{libprocess}} tests will allocate a {{Process}} on the stack and
then {{wait}} on that at the end of the test. If the test fails before the
process it waited on, however, {{gtest}} returns from the test function,
causing the stack variable to be deallocated. However, there is still a pointer
to in the {{libprocess}} {{ProcessManager}}, so when {{libprocess}} finalizes,
we end up throwing exceptions because the stack variable is trashed.
For example:
