Hmm sorry 🤔.
I'll rerun the release build artifact workflow for my project. Maybe it is then fixed. Else I would need to downgrade my dependencies versions

I can't see how it could possibly fix itself. I imagine you've updated the ubuntu build (or are using a Github tagged image that updated).

Let me know though when you've got a new build and I can test it.

There should be a new build online

Unsurprisingly building it again hasn't caused it to use an older glibc:

$ objdump -T /opt/compiler-explorer/ygen/bin/ylc | grep -Eo 'GLIBC_\S+' | sort -u
GLIBC_2.14)
GLIBC_2.16)
GLIBC_2.18)
GLIBC_2.2.5)
GLIBC_2.25)
GLIBC_2.28)
GLIBC_2.3)
GLIBC_2.32)
GLIBC_2.33)
GLIBC_2.3.4)
GLIBC_2.34)
GLIBC_2.38)

it's still linking against glibc 2.38 which is from 2023 https://sourceware.org/glibc/wiki/Glibc%20Timeline and is not in the Ubuntu 22.04 images we use.
