PROTON-1018: release transport context later in transport finalize
> Crash in pn_transport_finalize(transport.c) when logging level set to
> PN_TRACE_DRV
> ----------------------------------------------------------------------------------
>
> Key: PROTON-1018
> URL: https://issues.apache.org/jira/browse/PROTON-1018
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.10
> Reporter: Ganesh Murthy
> Assignee: Ken Giusti
> Priority: Minor
>
> When the logging level is set to PN_TRACE_DRV, the pn_ssl_free(transport)
> call ( inside the pn_transport_finalize(void *object)) logs messages.
> But the transport's context is prematurely freed and the logging framework
> that uses this context ends up crashing.
> Following is the backtrace from the qdrouter application-
> (gdb) bt
> #0 0x00007ffff7bc05ab in qd_transport_tracer (transport=0x7fffe4011710,
