----------------------------------------
Summary: [C++ binding] equality operator of nested lists causes
SIGABRT
Key: PROTON-1834
URL: https://issues.apache.org/jira/browse/PROTON-1834
Project: Qpid Proton
Issue Type: Bug
Components: cpp-binding
Reporter: Kim van der Riet
Attachments: test1.cpp
Checking the equality of nested list {{[[], [3, "hello"]]}} causes a core dump.
However, if the list (as a {{proton::value}}) is created and checked against
itself, it works fine. However, if the list is assigned to a message body and
then compared with the original, then the equality cores. The following is
dumped from the attached reproducer:
