When I commit and push my changes, I get these weird errors:
```

even though all tests succeed in Codespaces:
```
===============================================================================
All tests passed (5 assertions in 2 test cases)

```

Inizia con l’esecuzione di education/autograding@v1 e con il comando del Makefile che compila hello.cpp, quindi esamina catch.hpp in prossimità degli errori segnalati sigStackSize e altStackMem. Confronta l’ambiente del compilatore dell’autograder con l’esecuzione in Codespaces e verifica il completamento quando l’esempio viene compilato e le cinque assertions hanno esito positivo nell’autograder.
