Occasionally some process will output a very long line in an Emacs shell buffer (e.g. a multi-kilobyte Java class path). This frequently leads to a "stack overflow in regexp matcher" error, leaving the whole Emacs session unresponsive. Which regexp is causing this?

Does `M-x toggle-debug-on-error` get you a stack trace when this happens? – phils Oct 17 '18 at 22:01

Thanks phils. I'll set that and see. – kevin cline Oct 17 '18 at 22:47

Sadly no, the stack overflow just hangs the process. But I think the problem is in the process filter. I'm digging into that. – kevin cline Oct 18 '18 at 06:30
