I naively assumed that because llvm and clang are available in Trixie on riscv64 that I could simply install them and enable --with-llvm on copperhead, but I then discovered that this caused lots of segmentation faults and I had to revert the --with-llvm again. Sorry about not first testing without submitting results.

I had increased the core file size limit in /etc/security/limits.conf, but in Trixie this is overruled by a default /etc/security/limits.d/10-coredump-debian.conf. Moreover, the core_pattern was set by apport on the Ubuntu lxc host, but apport is not available in the Trixie lxc guest. I have now corrected both issues, and a simple test resulted in a core file being written to the current directory, like it was before the upgrade.

Best regards,
Tom
