It is the case when you use a default malloc, default memcpy, or default string functions from libc. In ClickHouse, we use jemalloc as a memory allocator and custom memcpy: https://github.com/ClickHouse/ClickHouse/blob/master/base/glibc-compatibility/memcpy/memcpy.h https://github.com/ClickHouse/ClickHouse/blob/master/base/gl...

But the usage of Musl is not related to Docker, because ClickHouse is a single self-contained binary anyway, and it is easy to use without Docker.
