When using faa22cc I wasn't able to get it to hang, but I can get it to segfault and drop a core file. The stack trace is pretty deep: Here are the threads when it segfaults |

I can get it to segfault pretty easily by adding some CPU stress at the same time the test is running. Run the test in a loop in one terminal, and then in a second terminal run
In another terminal. The test will segfault within a minute or two |

Seems to be the same as ros2/rmw_cyclonedds#118 |
|
Looking at the strack trace, I consider this ticket being the same as #329 @pbaughman please feel free to re-open if you still encounter this issue. |

I agree the segfault is fixed. It looks like the original hang might still be out there - I don't know what the cause of that was. |

I observed this failure in CI, and again on my machine. I was able to get a stack trace from GDB by doing
The stack trace is as follows:
I've got the following threads:
I've got version d630f8e right now, because we're not all the way up to date with dashing. I didn't see anything in the changelog or open issues that indicates this has been noticed before. I'm going to try to reproduce this on the nightly docker image next.
