alt Hacker NewsWhat makes you think it's a segfault? Does your shell print "Segmentation fault"? If so, you should be back at your shell and you should be able to recover the tab by typing 'reset' + enter (even if you can't see anything as you're typing it).
If nothing prints "Segmentation fault", this just sounds like a hang
I just had this happen today. It was indeed a segfault.
From what I could tell it looked like it was in JS code that had been JIT compiled. I haven't attempted to troubleshoot further beyond setting all my future Claude Code instances to pipe their stderr to disk so that I don't lose the stack trace next time.
