Title:
  spawn-based stackful coroutines terminate programs when used with
  asynchronous operations that have a completion signature starting with
  std::exception_ptr

Status in boost1.83 package in Ubuntu:
  Triaged
Status in ceph package in Ubuntu:
  New

Bug description:
  When stackful coroutines are used with asynchronous operations, and
  the completion signature starts with std::exception_ptr, the program
  is unexpectedly terminated during a SUCCESS scenario (SIGSEGV).

  This was noticed with the ceph package, and detailed here:
  https://github.com/canonical/microceph/issues/810

  This affects ceph 20.2.x when deployed on noble, which will happen on
  an upcoming noble release.

  This has been fixed in 1.84, but Noble uses 1.83, and can affect
  applications there.

  Upstream fix:
  https://github.com/boostorg/asio/commit/27c352f77d1806c7eed8ea91def6c4bc5f3715c1
