ERROR_DBG_PRINTEXCEPTION_C

What ERROR_DBG_PRINTEXCEPTION_C means

The debugger received the special exception used for debugger output related to a control event. In practical terms, this status belongs to debug output and console diagnostics: a debuggee communicates diagnostic text or control-event context through the debugger exception channel.

Typical causes

• The application or runtime emitted debugger-oriented output
• A console control event generated an informational debug exception
• A compatibility component uses legacy debugger notification conventions

How to investigate

1. Capture the accompanying exception parameters and output string
2. Verify that the debugger consumes the notification without treating it as a crash
3. Compare behavior with and without an attached debugger

Developer guidance

This status is usually informational inside the debug loop. Error reporting should retain the associated text but avoid alarming users with a false application-failure message.
