Execute rule operation, when given non-existing function for 'rule-text' parameter, is causing invalid free to occur when http api is shut down

Bug Report

iRODS Version, OS and Version

Tip of main

What did you try to do?

Execute a rule operation with a non-existing function, "writeline" (which was a typo, supposed to be "writeLine") then stop the http api container directly after.

Expected behavior

op_execute: RcComm::rError info = [status=[-1220000], message=[DEBUG:]] gets logged by the http api, and no message indicating an invalid free is occuring gets logged when shutting down the container.

Observed behavior (including steps to reproduce, if applicable)

The same message above gets logged, except free(): invalid pointer gets logged when shutting down the container.

Steps to reproduce:

1. Send execute rule request to the http api with a non-existing function passed to the 'rule-text' parameter
2. Shut down the container running the http api

I've tried to reproduce this against the following (all linux-based solutions):

• 0.3.0 release published on Docker hub
• A build later than tip-of-main (7b5ed8a)
• A Docker container running a build later than tip-of-main (7b5ed8a)

No attempt produced the results reported.

Given that this issue was reported from use of the Docker for Windows, it's possible the behavior stems from Docker running in a Windows environment.

I'll double check the implementation and see if anything stands out. Aside from that, I don't think there's anything actionable here without being able to reproduce it locally.
