RPC_S_ADDRESS_ERROR

The server faulted while accessing memory during the call

RPC_S_ADDRESS_ERROR represents an addressing exception raised on the RPC server. It is distinct from an invalid network address or endpoint. The server began executing the remote procedure and touched an invalid pointer, misaligned address, stale object, or corrupted structure, after which RPC reported the fault to the caller.

Obtain the server crash or first-chance exception stack and correlate it with the specific interface and opnum. Inspect ownership of context objects, user-marshaled types, output buffers, and asynchronous state that may outlive the call. Robust stubs validate wire data, but manager code remains responsible for its own pointers and object lifetimes.

What to inspect

  • Debug on the server and identify the exact faulting read or write.
  • Audit context-handle and async-object lifetime across threads.
  • Verify custom marshal routines allocate and free data symmetrically.
