I just noticed that on my compiler;
probably due to recent version, not sure.

0a229d80fd Respect maximum value of size_t in set_stream_size 
When size_t is 32-bits (like in a WASM project), passing in a 64-bit constant leads to compile-time warnings.

c743d0bf74 separated layout generation and saving 
Many example elfs (hello_32, hello_64, asm ...) require that the
first section directly follows the program header table. The
section header is then placed between segments or at the end.

This change prepares the late placement of section header table.
