[iOS] Application crashes when making a web request and using deep profiling with a "EXC_BAD_ACCESS" error



Reproduction steps:
1. Download and open the attached "DeepProfilingIssues" project
2. In the Build Settings window, switch to the iOS platform
3. Enable "Autoconnect Profiler" and "Deep Profiling Support"
4. Build and deploy the project
5. In the Editor window, open the Profiler window
6. In the Profiler window, switch the profiling target to your device and enable "Deep Profile"
7. On your device, press the button

Reproducible with: 2019.4.17f1, 2020.1.17f1, 2020.2.1f1, 2021.1.0b1, 2021.2.0a2
Could not test with: 2018.4 (Deep Profiling is not available)

Reproduced with: iPhone 12 Mini (iOS 14.1), iPhone 12 Pro (iOS 14.2.1), iPhone 6S (iOS 13.3.1)
Could not reproduce with: macOS Catalina 10.15.7, Nokia 7 Plus, Android 10, CPU: Snapdragon 660, GPU: Adreno (TM) 512

Note: from 2020.2 and up, the application doesn't crash but throws a "WebException" error in the console instead

  1. Resolution Note (2021.2.X):

    The WebException I could get was actually a message from exception in player that got also sent to Editor, and in my case it was a proper failure because I forgot to turn Wi-Fi on. Once I enabled Wi-Fi in iPhone, I started getting a debug message with reply from server. So, I conclude that in latest trunk everything works fine.

    For versions where the crash occurrs, the fix could be searched for and backported. Either way, I suspect this issue is not mobile specific, but rather profiler or scripting issue.
