WER_S_IGNORE_ASSERT_INSTANCE

WER handled this assertion instance

WER_S_IGNORE_ASSERT_INSTANCE is HRESULT 1769480 (0x001B0008) from winerror.h. AllStat describes it as “The assertion was handled.” In the Windows Error Reporting collection, queue, upload, archive, assertion, or debugging workflow, the value reports a nonfailure state that must not be collapsed into plain S_OK.

This result is actionable completion information and may require waiting, reconciliation, fallback, or user disclosure.

Where the status is encountered

  • WerReportSubmit and WER store processing; capture the exact API, object, and phase because the same numeric success severity does not define the state by itself.
  • Crash, hang, assertion, and application-failure reporting;
  • Enterprise policy controlling WER queue, archive, upload, debugger, and throttling;

Keep it attached to the operation that returned it. Interpreting it outside that API contract can turn a normal continuation or partial result into an incorrect retry or false completion.

What must be true before accepting it

Verify that the current assertion was intentionally ignored without creating a permanent rule for future occurrences. The boundary determines whether the caller continues, waits, falls back, or ends the operation.

Also confirm that returned outputs belong to the current operation generation and were not inherited from an earlier attempt.

Correct handling and recovery

Resume only the current execution path, record the exact assertion site, and keep future assertions eligible for normal handling.

Before repeating work after it, reconcile side effects and prove that the next attempt is idempotent.

Difference from nearby results

WER_S_IGNORE_ALL_ASSERTS creates a persistent ignore decision; this status applies only to this instance.

The neighboring result changes whether output is final, more work remains, or fallback is required.

Practical scenario

A developer dismisses one known assertion during a test run. The process continues, but the next assertion at that site is still reported.
