iOS app crashes on map load (radiusSearch) #1347

I'm seeing some occasional crashes on map load. Unfortunately I wasn't able to get a crash log with debug symbols.

It appears PointXYZ is not valid. https://github.com/introlab/rtabmap/blob/8c0e57bc52e9b4766db3e9d602153ae17d114f70/corelib/src/Rtabmap.cpp#L5008-L5009

Hi,

Thanks for reporting the issue. Just to clarify, when you say "on map load", do you mean after clicking on a map in the library, it crashes during the "Loading..." dialog box? The function radiusSearch() is used in many places (e..g, when searching nearest neighbors in point clouds). If you have a map that always crashes when you try to load, that could be useful if you could share it.

cheers, Mathieu

Sorry I forgot to follow up. The crash occurred when starting a new session before a map could be saved.
