Galactic CycloneDDS 0.8 check_whc Assertion failed crash

[NamanMM]

Hello everyone,

I have been getting the following failure (In the callback function of the node) resulting in the crash. It is sporadic and slightly tricky to reproduce but here is the error message:

/tmp/binarydeb/ros-galactic-cyclonedds-0.8.0/src/core/ddsc/src/dds_whc.c:284: check_whc: Assertion `whc->maxseq_node->next_seq == NULL' failed.

Any pointers or suggestion will be appreciated.
Thank you in advance.

Unfortunately Galactic is End-of-Life. Please try to reproduce the problem with one of the supported distributions (Humble, Iron, or Rolling), and re-open if necessary.

Galactic is end of life, but @NamanMM was kind enough to also create eclipse-cyclonedds/cyclonedds#1876: it definitely is a Cyclone DDS issue, and who knows if it still exists. I’ll follow up there as well
