Won't build on any Ubuntu newer than 21.04

[ptrxyz]

Sadly this does not work on Ubuntu 21.10 on wards. I assume it's because Ubuntu 21.10 (impish) installed libc6 (glibc) 2.34, which introduced a major ABI change. SIGSTKSZ is now no longer constant, and can’t be used directly to define array sizes.

I used Ubuntu 21.10, Boost libraries 1.74 and GCC9.

some excrept from the logs:

For reference, one thing I tried was to simply disable testing since it seems the problem is related to catch. No success though. :/

Still present as of today. Can we prioritize this as it's needed for the docker builds to work.

I'm bumping this up. Can you please take care of it? Would be a pity to fork this, just cause it's lingering around forever.
