Subject [jira] [Commented] (MESOS-3056) Slave segfault related to Synchronized
Date Fri, 17 Jul 2015 17:53:05 GMT

    [ https://issues.apache.org/jira/browse/MESOS-3056?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14631669#comment-14631669
] 

Jie Yu commented on MESOS-3056:
-------------------------------

I don't think it should block 0.23.0.

Since this is a memory bug, we don't even know for sure that's related to Synchronized.

As Mpark sugguested, we could add a CHECK to pthread_mutex_init so that if it fails, we'll
have a stack trace.
