I didn't try eshell. Thanks Arash and Corwin. The problem is caused by MSYS2 makepkg-mingw (the MSYS2 binary package builder) which adds -D_FORTIFY_SOURCE to CFLAGS. In fact, the MSYS2/Mingw-packages recipe for emacs-29 contains: # -D_FORTIFY_SOURCE breaks build CFLAGS=${CFLAGS//"-Wp,-D_FORTIFY_SOURCE=2"} # -foptimize-sibling-calls breaks native compilation (GCC 13.1) CFLAGS+=" -fno-optimize-sibling-calls" Once that is added to my recipe, the problem goes away.
