What's Wrong?

I use Claude-Code in a VM from VirtualBox that runs SuSE Linux.
After restarting the VM, I get a segmentation fault when starting Claude.
I tried to fix the issue with the help of our Windows desktop version of Claude and it suspected that Claude auto-updated to the newest version during the startup of the VM

The faulty Version is 2.1.138

The cpu type in the VM is "model name : 13th Gen Intel(R) Core(TM) i9-13950HX"

dmesg reports the following:
[19636.829792] show_signal: 44 callbacks suppressed

When I change the link used to start Claude so that it points to the old version, Claude runs again:
rm /lhome/gernjo/.local/bin/claude
ln -s /lhome/gernjo/.local/share/claude/versions/2.1.120 /lhome/gernjo/.local/bin/claude

What Should Happen?

Claude should either run with the VM or detect that it cannot use the VM and not silently install.

Steps to Reproduce

  1. Run Claude Code 2.1.120 in a Virtual Box VM running SuSE Linux
  2. Restart the VM
  3. Start Claude.
  4. Results in this message: "Segmentation fault (core dumped)"

Claude Model

Opus

Is this a regression?

Yes, this worked in a previous version

Last Working Version

2.1.120

Claude Code Version

Cannot run "claude --version" because this ends in a segmentation fault.
