The issue Based on the discussion in our libspdm issue (#2584) - especially the reply by @steven-bellock (https://github.com/DMTF/libspdm/issues/2584#issuecomment-1964454990) -, I issued the following commands in order to build the spdm-emu project:

user@ubuntu:$ git clone https://github.com/DMTF/spdm-emu.git
[...]
user@ubuntu:$ cd spdm-emu
user@ubuntu:~/spdm-emu$ git submodule update --init --recursive
[...]
user@ubuntu:~/spdm-emu$ mkdir build
user@ubuntu:~/spdm-emu$ cd build
user@ubuntu:~/spdm-emu/build$ cmake -DARCH=aarch64 -DTOOLCHAIN=GCC -DTARGET=Release -DCRYPTO=openssl ..

Judging by @alistair23 's reply in that issue (https://github.com/DMTF/libspdm/issues/2584#issuecomment-1963233389), -maccumulate-outgoing-args and -mno-red-zone should not even be used for the aarch64 build!?

Is my cmake command wrong, or is that a bug? I previously used exactly the same cmake command line in my separate clone of libspdm and there the lib builds without issues.

Thanks!

This is the same issue that the libspdm build flags had.
