Help to understand crash log

Hi! My Android build crashes on startup. I was looking though catlog, but the actual error line like ‘error signal 11 (SIGSEGV), code 1’ does not give me any clue where to start looking for the problem. Can anyone give some hints after taking a quick look at the catlog - it start when I launch app and end when it crashes.

It’s hard to say because it’s segmentation fault. Do you have any third party plugins installed? Your project is source code or Blueprint-only?

Looks like a crash during static initialization of libUE4.so on load. The callstack isn’t provided which will makes this a lot harder to track down. EIP is 0 so kind of difficult to tell where it crashed.

Was this a BP or code project? Did you use a binary release, or compile from source? Which plugins were enabled?
