Failure when built with -D_FORTIFY_SOURCE=3 suggests buffer overflows

[risicle]

NixOS now builds all packages with -D_FORTIFY_SOURCE=3.

This has caused the build of nanomq 0.18.2 to fail when generating idl_convert.h. This is on linux x86_64, gcc 12 when using idl_serial @ 908c364

See the build log @ https://gist.github.com/risicle/c31ff376e68f6336b71bcf5e7f1c8431#file-nanomq-0-18-2-build-log-L118 (original @ https://hydra.nixos.org/log/r8bwyihb2br676dmnrjjyl31gag74sga-nanomq-0.18.2.drv)

I don't see the "idl_convert.*" file generated from your log. Maybe you can try using only "idl-serial" to check if it fails.

@risicle I see the nanomq version stuck in 0.18.2 in NIXOS, do you need any further help?

Relevant PR: NixOS/nixpkgs#244685 (I am not the maintainer of this package, not totally sure why it has stalled)

I'm a maintainer of the package, build still fails on hydra, but local build is OK.
