@MiguelCompany eProsima/Fast-DDS#6371 could be related to this?
EDP matching path calls into security_manager().remove_reader() / remove_writer() and then into the cached listener->on_*_matched(...).
the new mutex narrows the listener-call window, which can let a matching callback fire after the security manager has begun releasing its shared_ptr, which may be producing the null deref the libstdc++ debug header catches.

i am not sure about this, but see possibility here. what do you think?

[MiguelCompany]

eProsima/Fast-DDS#6371 could be related to this?

I agree that this might have surfaced due to that PR (especially taking into account that it was merged the day before the first failure reported here), but the root cause is not related to those changes.

We will investigate.

@miguelgonrod @fujitatomoya We just opened eProsima/Fast-DDS#6404 that should fix this.

I ran a CI with those changes, and it seems to have worked:

I can't see this reproduced in the nightlies for one week, so I consider it fixed.
