[DISPATCH-1605] Leak of qdr_delivery_t (and associated message) on shutdown

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 1.10.0, 1.11.0
• Fix Version/s: Backlog
• Component/s: Router Node
• Assignee: Unassigned

Description

Occasionally the system_tests_console.py test will fail when run with CMAKE_BUILD_TYPE=Debug and -DRUNTIME_CHECK=asan

The issue is not console related - the unit test's use of test clients flushes out the problem.

ASAN error:
