ERROR_VERIFIER_STOP
Application Verifier stopped on a detected defect
ERROR_VERIFIER_STOP indicates that Application Verifier found a condition serious enough to stop or break into the process. The useful diagnosis is in the verifier message, debugger output, and stack trace, not in this generic code alone.
Typical findings
- Heap misuse, handle misuse, lock-order defects, or invalid API usage.
- Use-after-free, double close, corrupted synchronization state, or TLS errors.
- Incorrect COM, RPC, or loader behavior under verifier checks.
Diagnosis
Reproduce under a debugger with the same verifier settings. Capture the verifier stop number, parameters, stack, loaded modules, and dump. Identify the first invalid operation rather than the later crash it causes.
Handling
Do not catch and ignore the condition in production code. Fix the ownership, lifetime, or contract violation. Reduce verifier checks only to isolate a noisy subsystem, then re-enable the full relevant set before accepting the fix.
Testing guidance
Add a focused regression test and run it repeatedly under verifier because timing-sensitive defects may not reproduce on every execution.
