ERROR_LONGJUMP

What ERROR_LONGJUMP means

A long jump performs non-local control transfer, bypassing ordinary returns. The status is usually part of unwinding machinery rather than a user-facing failure, but it matters when debugging destructors, cleanup handlers, or corrupted stacks.

Where it appears

  • setjmp/longjmp based runtimes
  • language runtimes implementing non-local exits
  • debuggers and crash analyzers observing exception dispatch

Likely causes

  • an intentional longjmp call
  • runtime implementation of cancellation or error escape
  • stack corruption falsely resembling a valid jump context

What to collect

  1. jump origin and destination stacks
  2. saved jump-buffer contents and owning thread
  3. resources acquired between setjmp and longjmp
  4. compiler, runtime, and exception model

How to respond

For intentional use, ensure every skipped resource has an explicit cleanup strategy; C++ objects with automatic destructors make raw longjmp especially dangerous. For unexpected occurrences, capture a dump and inspect stack integrity rather than retrying the operation.
