isocpp2 Listener Aborted (core dumped)

The Listeners that I try to run, compiled with isocpp2, all result in:

=== [ListenerDataSubscriber] Set listener  
=== [ListenerDataSubscriber] Ready...
video_displayer: /opt/DDS/opensplice/src/kernel/code/v_status.c:515: v_statusReset: Assertion `s != NULL' failed.
Aborted (core dumped)

This error is thrown when the data writer starts writing data. Both the OpenSplice example and my own code result in this error.

Stack trace of the error:

How can I solve this problem?

Dear kjrusscher,

I have just tested the Listener example code. it is working fine.

~/Softwares/OpenspliceDDS_CommunityEdition/PXXX-VortexOpenSplice-6.9.190925OSS-HDE-x86_64.linux-gcc9-glibc2.27-installer/HDE/x86_64.linux/examples/dcps/Listener/isocpp2$ ./subscriber
=== [ListenerDataSubscriber] Set listener
=== [ListenerDataSubscriber] Ready ...

=== [ExampleDataReaderListener::on_data_available] - samples.length() : 1
=== [Subscriber] message received :
userID : 1
Message : "Hello World"

=== [ExampleDataReaderListener::on_requested_deadline_missed] : triggered

=== [ExampleDataReaderListener::on_requested_deadline_missed] : stopping
=== [ListenerDataSubscriber] Closed

With best regards,
Vivek Kumar Pandey

Quite strange. I removed all OpenSplice builds from the install directory and did a new build of OpenSplice. After that the error had disappeared. I guess something went wrong during the previous build.
