This is a good point! Based on it, I just defined task #16035.

Hopefully when task #16035 is complete, we can also close this bug :-).

Commit 3a1b967 includes the option --enable-sse2 for cfitsio :

$ egrep -n -C2 "sse2|avx" reproduce/software/make/*.mk
reproduce/software/make/high-level.mk-428-      export gbuild_tar=$(ddir)/$$customtar
reproduce/software/make/high-level.mk-429-      $(call gbuild, cfitsio-$(cfitsio-version), , \
reproduce/software/make/high-level.mk:430:                     --enable-sse2 --enable-reentrant \
reproduce/software/make/high-level.mk-431-                     --with-bzip2=$(idir), , \
reproduce/software/make/high-level.mk-432-                     make shared fpack funpack)

This is likely to cause an arm64 portability bug, as in https://savannah.nongnu.org/bugs/?61026 . Unless we want an Intel-compatible-only package, then the option should be removed, pending a method of enabling the option only for Intel-compatible architectures.

(This should affect the reproducibility of gnuastro projects on arm64.)
