segfault in sails app on Node 18

**Environment Information**
- Alpine 3.17
- 18
- NPM Version [e.g. 5.4.2]:
- C++ Toolchain [e.g. Visual Studio, llvm, g++]:
- node-rdkafka version 2.15.0

I have a sails app that creates a producer in api/service. But I immediately get a segfault when the producer tries to connect to ana ccessible host. I do not get this when running the same app on a dev system that is not using alpine.

I installed hte system dependencies outlined in the Docker readme of this repo for alpine.

Start with the Docker README's Alpine dependency instructions and reproduce the producer connection on Alpine 3.17 with Node 18 and node-rdkafka 2.15.0, comparing it with the non-Alpine system. Review the native binding and librdkafka connection path using the missing NPM version and C++ toolchain details. Done means identifying a reproducible cause and confirming the producer no longer segfaults in the stated environment.
