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";

Bug#1005906: additional testing

Also failing for 2.33-1 (as found in 'debian:testing-20211220' docker image): root@3385b6c8f2c8:/# if test -x /usr/bin/head; then echo "/usr/bin/head is executable"; else echo "dead beef"; fi; dpkg-query -l libc6 dead beef Desired=Unknown/Install/Remove/Purge/Hold |

Bug#1005906: additional testing

Bug exists for 2.33-3 [as in current "debian:testing" docker image]: root@d6c1df8a7f2f:/# if test -x /usr/bin/head; then echo "/usr/bin/head is executable"; else echo "dead beef"; fi; dpkg-query -l libc6 dead beef Desired=Unknown/Install/Remove/Purge/Hold |

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

Bug#1005906: r-base strace

Sorry, I was using the wrong base docker image in that last test. Here's an strace from 'rocker/r-base:4.1.2' + 'apt-get update && apt-get install strace': execve("/usr/local/bin/test_executable.sh", ["test_executable.sh"], 0x7ffd6cca52a0 /* 7 vars */) = 0 brk(NULL)

Bug#1005906: working strace

I noticed that installing 'strace' didn't trigger the libc6 install, so here's a working strace (prior to libc6 upgrade): execve("/usr/local/bin/test_executable.sh", ["test_executable.sh"], 0x7ffc0826c210 /* 5 vars */) = 0 brk(NULL) = 0x55706ff12000
