Package: libc6 Source: glibc Version: 2.24-11+deb9u1 likely also triggered in other ways (eventhough masked when using a dso), but the following seems to be an easy way to replicate :
$ echo -e '#include <stdio.h>\n#include <errno.h>\nint main() {printf("%d\\n", errno); }' > t.c $ gcc -static -o t t.c $./t 2 the problem is on the patch[1] to add the /etc/ld.so/nohwcap flag and that is not resetting errno after it fails to find that file.
