Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When an app crashes, not all output is shown.

This is not an issue in the User Terminal or in a standard OS terminal.

Steps to Reproduce

I have an app, lots of printf debug statements, it currently crashes with a segfault. None of the printf is visible in the Agent Terminal.

If I flush after each printf, or use fprintf to stderr, then the output is visible.

Expected Behavior

The full output is show without requiring flush statements.
