Redis [CRASH] Custom module works in debug but not release mode

Crash report

A module is involved, but it's my own doing. Version of Redis is 7.0, and I've tried both a local install and the Docker image with the same result. Basically, I have a need to have boost::geometry server-side on Redis, and I've been using C++14. When I run in release mode using CLion, the seg faults happen in my first pic below, and the second pic is the call stack. If I need to, I can share very similar code.

I've verified with cout statements that all of my save commands go through okay in release mode, so this is happening with something after that when Redis wraps up the save. When I run it with Valgrind with the module built in release mode, it saves the RDB just fine (sample output after crash report), and compiling with -Wall doesn't show anything too frightening. I am just dipping my toes back into C/C++, so I am very confused.

Comment From: herter4171

Figured it out. In my use of RedisModule_CreateDataType, I had a non-pointer RedisModuleTypeMethods passed in via &, so apparently it was going away.
