How this service works
Prüft den behaupteten erreichten C++-Catch-Frame und die determinate Destruktorreihenfolge einer anonymen Unwind-Sicht.
Output
A validation result indicating whether the claimed catch frame index is correct for the given C++ exception unwind scenario, along with determinate destructor ordering correctness for the anonymous unwind view.
Example use cases
Validate catch frame for thrown exception
“I have a C++ unwind scenario where the thrown type is index 1, the type hierarchy has two entries (one with a null parent, one with parent 0 and public_base true), and two stack frames with handlers [0] and [1,2] respectively. Can you check if the claimed catch frame index 1 is correct?”
Verify destructor order with escaping throws
“In this unwind scenario, some stack frame objects have escaping_destructor_throw set to true — can you verify that the claimed catch frame index 2 is still correctly selected and the destructor ordering is determinate given those flags?”
Test RTTI type hierarchy matching for exception handler
“I need to validate whether exception type index 4 would be caught by handler type index 2 given this type inheritance hierarchy, with the claim that frame index 3 is selected — can you check that for me?”

Endpoint
POSThttps://detect.halowerk.com/v1/F-A-NEXT-CPP_UNWIND/cpp-exception-unwind-handler-selection?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify C++ exception unwind handler selection logic — particularly when testing compiler behavior, validating runtime type information hierarchies, or checking determinate destructor ordering in complex stack unwind scenarios involving multiple frames and type inheritance.
Side effects
- Invalid claim value outside allowed numeric range
- Type array or frame array exceeding 512 items
- Malformed type hierarchy with missing required fields
- Circular or inconsistent parent references in type list
- Missing required cpp_unwind fields returning 400 error
- Ambiguous or indeterminate destructor order detected
