Benjamin Bannier commented on MESOS-6985:
-----------------------------------------
[~ipronin] Would you mind sharing your POC? I would be interested in a fix for
MESOS-3475 which I suspect to be linked and which caused issues like the one
reported here in a number of places.
> os::getenv() can segfault
> -------------------------

> Key: MESOS-6985
> URL: https://issues.apache.org/jira/browse/MESOS-6985
> Project: Mesos
> Issue Type: Bug
> Components: stout
> Environment: ASF CI, Ubuntu 14.04 and CentOS 7 both with and without
> libevent/SSL
> Reporter: Greg Mann
> Assignee: Ilya Pronin
> Priority: Major
> Labels: flaky-test, reliability, stout
> Attachments:
> MasterMaintenanceTest.InverseOffersFilters-truncated.txt,
> MasterTest.MultipleExecutors.txt

> This was observed on ASF CI. The segfault first showed up on CI on 9/20/16
> and has been produced by the tests {{MasterTest.MultipleExecutors}} and
> {{MasterMaintenanceTest.InverseOffersFilters}}. In both cases,
> {{os::getenv()}} segfaults with the same stack trace:
> {code}
