Could you use either a git formatted patch or a Salsa merge request for further iterations of this submission? I believe debian/tests/compile-and-execute should be marked as executable since it's a shell script but that information is not encoded in your diff file.
I believe it is more convenient for most Debian maintainers if you don't edit debian/changelog directly but write an appropriate commit message that can be used by gbp dch. When I tried building this with sbuild for Debian Unstable today, I got this error: autopkgtest [12:04:48]: test compile-and-execute: [----------------------- + trap rm o 0 + pkg-config --cflags --libs libhwy + cflags=-DHWY_SHARED_DEFINE -lhwy + c++ -x c++ - -o o -fsanitize=address -Wall -Wextra -Wpedantic -DHWY_SHARED_DEFINE -lhwy + ./o ==83347==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. + rm o Thank you, Jeremy Bícha
