Debugger Freezes When Inspecting Large Array

Type: Bug

When debugging a C++ console application in Visual Studio Code, the debugger freezes when attempting to inspect a large array (1,000,000 elements) in the "Variables" panel, even though GDB's print limit is set to 100 elements and VS Code's debug view is configured to display only the first 1,000 elements. This issue causes the debugger to become unresponsive, preventing further debugging.

Start by reproducing the freeze in a C++ console application with a 1,000,000-element array, using the Variables panel with GDB's print limit at 100 and the debug view limited to 1,000 elements. Compare behavior with the reported VS Code and C/C++ extension versions; done means inspecting the array no longer makes the debugger unresponsive.
