Question by MikDab · Mar 11, 2019 at 11:16 AM · android buildil2cppstackcorrupt

Android build crash - stack corruption detected Unity 2018.3.8f1

Hi,

I've been consistently experiencing the same type of crash in my android build and I can reproduce it reliably. It happens at a specific point in the game 100% of the time. I've looked into GC, memory issues, bad code which could cause leaks or anything of the sort. Tried numerous different settings (mono, Il2cpp, .Net 2.0 & .Net 4.x, different architectures, different android API versions, etc.) when building the game, the crash still happens. The profiler doesn't show anything suspicious. It only happens when I build to android, and not in the editor or standalone. The game currently is quite small.

  • Details on the circumstances of the crash:

A mesh, upon hit by a collider, is being "cut" into two new meshes. These meshes, upon instantiation, are given rigidbodies (only the parents), and convex mesh colliders. Some of the meshes before the "cut" are baked (because some of them are skinned meshes). The crash only happens upon the first "cut" on the initial skinned mesh (the new mesh pieces can be cut as well, and that happens a lot, but none of the crashes have happened after the initial cut was successful).

  • Crash report

This is the most informative crash report I have received as of yet. At first I thought that there was some sort of memory leak. But now it seems that the physics are involved? (app name is hidden)

This crash occured after about 20 minutes of runtime (Android 8.1)

Quoting myself: "Tried numerous different settings (mono, Il2cpp, .Net 2.0 & .Net 4.x, different architectures, different android API versions, etc.) when building the game, the crash still happens".

Answer by MikDab · Mar 11, 2019 at 06:04 PM

I've narrowed down why the crash happens. It's strange that Unity does not provide any warnings/errors in the editor when doing this, since it is extremely confusing and throws off the scent of the problem.

The problem potentially lies with the fact that baking/assigning meshes and setting them to convex (with the intent of using the collider together with a rigidbody) during runtime potentially produces extremely over-the-limit convex mesh colliders (way over the suggested 255 triangle limit as stated in the documentation). The editor can handle this, does not produce errors/warnings that the convex mesh is over the limit and might cause crashes, while Android crashes unexpectedly without reasonable errors to go on.

Even though this is partially my fault, I still think that there should be at least a warning in the console when setting meshes to convex at runtime, indicating whether or not the mesh is suitable for use and the potential dangers.

Thanks MikDab, I had exactly the same problem as yours and changing mesh colliders really helped!
