[GitHub] [tvm] jplu opened a new issue, #11387: [Bug] Crash with a segmentation fault on Apple M1 Metal device

jplu opened a new issue, #11387:
URL: https://github.com/apache/tvm/issues/11387

   I'm using a TVM model into a Swift app. The way I do it is that I code all the TVM related stuff in C++ using the `libtvm_runtime.dylib` and then call it from Swift. The model I have is targeted for Metal. Everything is working fine when I run the app from the CLI, but crashs when I run the tests. Please note that the CPU version of the model works as expected including during the tests.
   
   ### Expected behavior
   
   Tests are working with the Metal version of the model.
   
   ### Actual behavior
   
   The Metal version of the model crashs when running the tests.
   
   ### Environment
   
   OS version: MacOS Monterey 12.4
   TVM version: Commit 8d4f4dd73ff2d762ade38aa0f9e8e9fba5f933da
   
   ### Steps to reproduce
   
   Difficult to reproduce but I can give many details. The call that crashs in my code is:
   ```
   tvm::runtime::Module gmod = this->model.GetFunction("default")(dev);
   ```
   Where `dev` is defined by:
   ```
   DLDevice dev = {kDLMetal, 0};
   ```
   
   I have also made so screen shots of the stack trace. First call:
