MessageFilterDisplay Crash

[StefanFabian]

After updating, I'm getting the following crash when starting RViz with a config that contains a GridMap display.

Stacktrace says the relevant line is: https://github.com/ANYbotics/grid_map/blob/b4376234e7a9edadca1bb1302a4b27f2374637e3/grid_map_rviz_plugin/include/grid_map_rviz_plugin/modified/message_filter_display.h#L105

If I replace that call with a fixed number, e.g. 100, it crashes at the access of queue_size_property_ in subscribe. If I replace that, too, everything works fine. I don't have a clue why queue_size_property_ is invalid, though. The debugger won't show any member of _RosTopicDisplay maybe that is related.

Hey @StefanFabian, we did not observe that issue yet.

Can you share a core dump?

Can you share your ROS version?

[StefanFabian]

Sorry for the late reply, I was occupied with a paper deadline. I'm on Melodic. I'll check if I can figure out what's happening or get a core dump in the next few days.

Hi @StefanFabian & @maximilianwulf,

Please refer to my comment in elevation_mapping Issue #141 which was closed.

Thanks!

Can someone check if rviz changed this property recently?
