UE4.15.1 Crashes when I create a new C++ class.
This specific bug has recently been noticed but I have no idea when it started. I'll try to make a new C++ file via the editor, and it will immediately start a recompile. It'll get stuck at about 86% as it compiles, and then it crashes with the following log linked here.
The file still gets created but I have to compile it in VS to actually use it. It makes creating a set of new C++ files an absolute pain and really slows everything down.
Not sure what this means or what in my project could be causing this to fail. If I could get a pointer as to what I should be fixing it'd be much appreciated. Don't have a lot of time to be debugging engine issues.
Your callstack matches a known issue that you can follow in the public tracker here: https://issues.unrealengine.com/issue/UE-35710 . Looking at the callstack, it appears to be related to the use of hierarchical instanced static meshes. Since the last call before the crash is to serialize the HISMs, it seems like something in their construction/setup is causing the problem. If you are using HISM somewhere in your project (either in code or editor), I would suggest removing them temporarily to see if the crash continues to occur.
