Crash on Mac OS X due to dlopen not being thread-safe
-----------------------------------------------------
Key: MESOS-164
URL: https://issues.apache.org/jira/browse/MESOS-164
Project: Mesos
Issue Type: Bug
Environment: Mac OS X 10.7.3
Reporter: Matei Zaharia
I get a crash fairly deterministically that seems to be due to the Python
library calling dlopen() in a separate thread from the main thread. I've
included a stack trace in GDB below. The reason I think it's due to thread
unsafety is the comments on
http://stackoverflow.com/questions/8744608/dlopen-in-multithreaded-application-exit-with-trace-bpt-trap.
