Ilya Pronin commented on MESOS-6985:
------------------------------------
[~vinodkone], sorry I missed the comment somehow. I have a POC-like patch for
this, didn't have time to finish it. I'll try to finish it maybe next week.
Feel free to reassign if somebody would like to work on it before that.

> 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}
