Bug#1005906: additional experimentation
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: 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

Bug#1005906: strace from rocker/r-base:4.1.2
Sorry, I got the base image wrong when experimenting with strace. Here's my
updated Dockerfile. I've confirmed that this bug still happens when I *only*
install libc6 (and dependencies):
--- begin Dockerfile ---
FROM rocker/r-base:4.1.2
COPY ./test_executable.sh /usr/local/bin
RUN test_executable.sh # works
RUN apt-get update && apt-get install -y strace
RUN test_executable.sh # works
RUN apt-get install -y libc6
RUN test_executable.sh # doesn't work
--- end Dockerfile ---
Working:
ii libc6:amd642.32-4 amd64GNU C Library: Shared libraries
Not working:
ii libc6:amd642.33-5 amd64GNU C Library: Shared libraries
When installing/upgrading libc6, apt also installs the following packages:
libc-bin libc-dev-bin libc-l10n libc6 libc6-dev locales
