[Crash] SIGSEGV: invalid attempt to access memory at address 0x3

I’m getting constant crashes when I try to save my work or play test the game. It doesn’t happen every time I save or play in editor, but maybe 1/3 to 1/2 of the time.

Here’s the error message I’m getting:

SIGSEGV: invalid attempt to access memory at address 0x3

EngineCrashHandler(FGenericCrashContext const&) [in UE4Editor) + 15
, line 72969273] [in UE4Editor]
PlatformCrashHandler(int, __siginfo*, void*) [in UE4Editor-Core.dylib) + 95
, line 72969273] [in UE4Editor-Core.dylib]
_sigtramp() Address = 0x8bf265aa (filename not found) [in libsystem_platform.dylib]

Setup:

  • MacBook Pro 15" Retina 2012
  • OS X 10.9.4

I’ve been working with UMG recently and I think this may be related to widget variable binding, but I’m not sure. I do know that I haven’t been crashing with this error message before 4.4.0.

I also moved a folder of blueprints outside of the project folder (and re-integrated it manually), which may have messed up some internal references (?). However, I don’t notice any in-game bugs when I play in editor.

Any help is appreciated.

Hi,

It should have been fixed now by the latest hotfix “4.7.3” : https://forums.unrealengine.com/showthread.php?63262-4-7-3-Hotfix-is-live!

Can you confirm ?

Thanks
