bschofield opened a new pull request #8312:
URL: https://github.com/apache/pulsar/pull/8312
Fixes #8311
### Motivation
The C/C++ glue code in *c_Producer.cc:handle_producer_send()* has a memory
leak. Specifically, a `pulsar_message_id_t` is created but never freed. This
leaks one object for every asynchronous message send, which adds up to a big
problem if sending lots of messages.
### Modifications
After calling the C callback, `delete` the memory allocated for the
`pulsar_message_id_t`.
### Verifying this change
I have manually verified that this change fixes the leak, using _valgrind_.
This change is a trivial rework / code cleanup without any test coverage.
