Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Crashing on launch

When i open my project it appears this message:

SIGSEGV: invalid attempt to access memory at address 0x3

EngineCrashHandler(FGenericCrashContext const&) Address = 0x8b5a38f (filename not found) [in UE4Editor] PlatformCrashHandler(int, __siginfo*, void*) Address = 0x8c8b4df (filename not found) [in UE4Editor-Core.dylib] _sigtramp() Address = 0x91d29f1a (filename not found) [in libsystem_platform.dylib]

How can i fix it? I really need to get my project back as soon as possible in order to submit it for university.

Sorry if i didn't write anything. I managed to solve the problem converting the project from 4.3.1 to 4.4. But i'd like to understand anyway way my unreal is crashing just on the versione 4.3. The crash is always at the start when i try to open the project. Let me know if you need further information

If the crash was happening in 4.3 but not in 4.4, then we probably found the bug in 4.3 and fixed it in the next release (4.4).

That log file doesn't appear to be a crash log. It's a text document saying "Just a record of success."
