Android Crash: Libunity.so crashes while allocating memory on scene start/load

Unity Engine

Here is the log output for a consistent crash on my device (Google Nexus 5x). If I’m reading the log correctly, it’s trying to allocate memory (this happens as it’s switching scenes), and since libunity.so is the culprit, this isn’t something I can fix?

Per the logs, you can see the game is using ~47mb of memory, which doesn’t seem excessive? Also based on the log screen, you can see the exact adb logcat settings I’m debugging with.

I’ve tried:

  • Unity 5.6.3f1, 2017.1, 2017.2, it crashes on all versions.
  • Not doing anything exotic, Internal build system, it’s on Mono2x backend, .Net 2.0 subset, no stripping etc.
  • I can run the same level for hours no crash, it only happens upon level switch (where it appears to be trying to clear and reallocate memory).

Any ideas? Have I read the logs correctly and this is a Unity bug outside of my control?

Just a bumpity bump, am I correct in the above post in determining it’s a Unity bug that I can’t fix and I should just submit a bug report to Unity?

Can confirm this happens on multiple devices, same crash, same conditions.

Most certainly submit it.
Don’t forget to attach the project that reproduces it (If you’re able, stripping it down to smallest reproducible version really helps), devices that experience this (Sometimes helps to narrow down on the problem) and if there are any special steps to do for reproducing this.
Also, post the Case ID : )

UPDATE: Submitted, Case 947531. I stripped it down to 2gigs from 4gigs so it took hours to send, but I did it!
