In case you&#x27;re binary-size-obsessed like me, here are some stats on that statically-linked musl &quot;Hello, World&quot; binary:<p><pre><code>    $ size target&#x2F;x86_64-unknown-linux-musl&#x2F;debug&#x2F;hello
       text	   data	    bss	    dec	    hex	filename
     351471	  10256	  10064	 371791	  5ac4f	target&#x2F;x86_64-unknown-linux-musl&#x2F;debug&#x2F;hello
</code></pre>
Here is a &quot;Hello, World&quot; C program statically linked against musl:<p><pre><code>    $ size test
       text	   data	    bss	    dec	    hex	filename
       3380	    248	   1232	   4860	   12fc	test
</code></pre>
Looking at a size profile, about 25% of the static Rust binary comes from jemalloc, which is strange since musl doesn&#x27;t seem to use jemalloc?
