Console errors are thrown when trying to save Profiler frames bigger than 2GB

Profiling

-

Reproduction steps:
1. Create a new project
2. Import "ScriptThatCreatesHugeStacktrace.cs" to the project
3. In the toolbar, select "Window" > "Analysis" > "Profiler"
4. In the Profiler window, enable "Deep Profiling"
5. In the Profiler window, select "Editor" profiling
6. In the Profiler window, enable recording
7. In the toolbar, select "Test" > "Profiler"
8. After a few seconds, disable Profiler recording
9. In the Profiler window select the frame where the calculations were run (the biggest frame)
10. Save the frame

Expected result: The selected frame is saved
Actual result: The selected frame isn't saved, an error appears in the Console window: Unable to save profiler frame ... to file "...": frame size is larger than 2GB UnityEditorInternal.ProfilerDriver:SaveProfile(String) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Reproduces on: 2018.4.26f1, 2019.4.6f1, 2020.1.0f1, 2020.2.0a19

  1. Resolution Note (2020.2.X):

    The current behavior is by design - the maximum frame size profiler can serialize is 2GB.
    We consider this issue as a severe and are going to address it in the future version of Unity as it requires underlying design changes.
