OSS_COMPARATOR_DLL_NOT_LINKED
OSS_COMPARATOR_DLL_NOT_LINKED (0x80093024) is an OSS ASN.1 runtime result for generated-value comparator DLL absent. The runtime cannot load the optional module used for schema-aware comparison of ASN.1 values. Because comparison API and ASN.1 type is central to this condition, Microsoft’s HRESULT range and the OSS Nokalva return-code documentation should be read together. Start the investigation by recording comparator DLL resolution and dependencies, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
Similar names, different faults: OSS_COMPARATOR_DLL_NOT_LINKED
Bytewise comparison is not generally equivalent to ASN.1 value comparison, especially with pointers, defaults, SET ordering, or multiple BER encodings.
Where processing stopped
At the generated-value comparator DLL absent boundary, capture the first OSS function returning the value and note whether the operation was encode, decode, copy, compare, constraint validation, or trace setup. Preserve the selected PDU, encoding rules, and semantics required for absent/default components; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Isolation sequence
- Compare identical independently allocated values
- exercise optional and defaulted fields
- Confirm the generated and runtime versions match
Facts that change the conclusion
- comparison API and ASN.1 type
- comparator DLL resolution and dependencies
- semantics required for absent/default components
Instrumentation
Where comparison API and ASN.1 type can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use comparator DLL resolution and dependencies together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Completion check: the result
Package the comparator module and validate equality semantics with structurally different but equivalent test values.
