[BUG] Claude code is killed by OOM killer due to subprocess issue
Preflight Checklist
- [x] I have searched existing issues and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code
What's Wrong?
When claude code is launching a program - it launches it in a way that Linux OOM killer targets claude code instead of subprocess. When claude code is working in tmux - session immediately terminates with "Pane is dead (signal 1" and it is getting not trivial to recover.
What Should Happen?
Subprocess is launched in a way that OOM killer only kills subprocess, and claude code correctly receives error message and can understand that process was killed by OOM killer.
Error Messages/Logs
No logs were generated.
tmux pane terminates with "Pane is dead (signal 1"...
Steps to Reproduce
- Make claude code write a C++ program that malloc's memory in infinite cycle and run it
- Wait

Additional Information
It might have worked sometimes in the past - I think I saw it noticing program termination and guessing it was killed by OOM killer. It is not unthinkable to get this error: if one runs 4 claude code's and they sometimes run heavy programs, one day you won't be lucky - they all will overlap and crash claude code. If it was gracefully failed - claude code would have been able to recover and proceed.
