Segmentation fault (core dumped) after all workers are done

[patrou]

Hello,

I am writing a script in which I spawn n workers, I assign them a task, when they finish they post a message with the result and they are done. When all threads are done, a callback is returned to continue with the main execution of the program.

The above code produces Segmentation fault (core dumped). It happens very rarely in the end of the program after all results are collected and printed in the main thread. In a VM environment, it happened 6/5040 times. In other platforms happens with different ratio or never.

I, also used the --trace_gc flag. But, I noticed that Segmentation fault can be caused with or without any flags.

Any suggestion will be helpful.
