Outside Debian (so I'm not sure how helpful this is), the bug doesn't exist in the latest ' frolvlad/alpine-glibc ' docker image [Alpine linux], which from the looks of it seems to be libc v2.34:
/ # if test -x /usr/bin/head; then echo "/usr/bin/head is executable"; else echo "dead beef"; fi; apk info glibc /usr/bin/head is executable WARNING: Ignoring https://dl-cdn.alpinelinux.org/alpine/v3.15/main: No such file or directory WARNING: Ignoring https://dl-cdn.alpinelinux.org/alpine/v3.15/community: No such file or directory glibc-2.34-r0 description: GNU C Library compatibility layer glibc-2.34-r0 webpage: https://github.com/sgerrand/alpine-pkg-glibc glibc-2.34-r0 installed size: 4444 KiB ... but it also doesn't exist in the 'frolvlad/alpine-glibc:glibc-2.33' docker image: / # if test -x /usr/bin/head; then echo "/usr/bin/head is executable"; else echo "dead beef"; fi; apk info glibc /usr/bin/head is executable WARNING: Ignoring https://dl-cdn.alpinelinux.org/alpine/v3.15/main: No such file or directory WARNING: Ignoring https://dl-cdn.alpinelinux.org/alpine/v3.15/community: No such file or directory glibc-2.33-r0 description: GNU C Library compatibility layer glibc-2.33-r0 webpage: https://github.com/sgerrand/alpine-pkg-glibc glibc-2.33-r0 installed size: 9224 KiB
