Hey @sergey-safarov,
What are you compiler options that resulted in this warning?
I tried to replicated this on `Alpine Linux v3.22` with gcc `gcc version
14.2.0` but i could not replicate this warning.
Steps i used was:
1. Provide addiotional compile flags to compiler to be more verbose on config
step:
`CFLAGS='-Wall -Wmaybe-uninitialized' cmake -S . -B build-alpine-redis
-DINCLUDE_MODULES="ims_qos_npn" -DCMAKE_INSTALL_PREFIX=install/alpine-redis
--fresh`
2. Try to build with verbose mode to see the flags:
`cmake --build build-alpine-redis/ -j8 -t ims_qos_npn -v`
result in:
``` c
cd /code/build-alpine-redis/src/modules/ims_qos_npn && /usr/bin/cc

```
`-Wall` and `-Wmaybe-uninitialized` are present.
But there is no warning about uninitialized variables on my side.
I also tried this on Ubuntu with `gcc version 10.5.0 (Ubuntu
10.5.0-1ubuntu1~20.04)`, with the same results
