Scary compile errors/warnings on alpine linux

[AlexanderSchuetz97]

This is the error:

This is some buffer overflow error?

The error is present in the current "head/master" of the git repo and the last release tarball and can be reproduced with an alpine linux docker container.
This is the Dockerfile I am using for the container that gets this error:

FROM alpine:latest
RUN apk add nasm git alpine-sdk bash cmake ninja meson perl autoconf automake libtool gperf xz libogg yasm diffutils gawk linux-headers asciidoc doxygen xmlto

To compile I run:

mkdir -p openh264/build
cd openh264/build
meson setup --default-library=static .. --prefix "/project/target" --libdir="/project/target/lib"
ninja

Using the git repositorys head, the ninja build fails because the warning is treated as error.
Using the last source tarball I get a warning with the same content but the build continues.
