Hi,
We have some weird crashes happening in our project. The crashes happen in the engine code. So in order to debug them, I tried running the project through the engine source project by passing the path of our project into the engine project. I’m running the engine project on OSX in XCode. I have the latest source for 4.8.1 and the project is built with the 4.8.1 engine binaries.
When I run the project through it’s own xcode project, I can load into the editor fine, but I get a crash when loading a specific map. However, when running through the engine source project, I get a crash while the editor’s loading, deep in the call stack usually in the FLocalizationManager in some lookup table.
This crash doesn’t happen when running the project editor as a stand alone or through the projects xcode project. I also noticed that when I try to view the FName of the object it’s trying to load, I see this error in the xcode log window:
Traceback (most recent call last):
File “/Users/Shared/UnrealEngine/4.8/Engine/Extras/LLDBDataFormatters/UE4DataFormatters.py”, line 72, in UE4FNameSummaryProvider
return ‘name=’ + Val
TypeError: cannot concatenate ‘str’ and ‘NoneType’ objects
I have tried running the same project with a blank map as the default map and the editor loads fine. So it’s definitely something in our map. But I haven’t the slightest clue as to how to track it down because the information we get from this crash is inconsistent.
