> Key: PROTON-2517
> URL: https://issues.apache.org/jira/browse/PROTON-2517
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.37.0
> Reporter: Clifford Jansen
> Assignee: Clifford Jansen
> Priority: Major
>
> See the C++ frame trace from
> https://issues.redhat.com/browse/ENTMQCL-3278
> The zero length array is printed instead of a null because the test in
> emit_multiple() from emitters.h fails to set the current node of the
> pn_data_t to the first node. The test
> if (pn_data_type(data) == PN_ARRAY) { //...
> fails and the array processing logic is bypassed, including the lines
> switch (pn_data_get_array(data)) {
> case 0:
> pni_emitter_writef8(emitter, PNE_NULL);
