I encountered this when sending a COMMAND ending in a backslash to the inferior comint process, and getting Debugger entered--Lisp error: (invalid-regexp "Trailing backslash"). E.g. M-x comint-run RET cat RET M-: (comint-redirect-results-list "\\" ".+" 0) Debugger entered--Lisp error: (invalid-regexp "Trailing backslash") (looking-at "\\") (comint-redirect-results-list-from-process #<process cat> "\\" ".*" 0) (comint-redirect-results-list "\\" ".*" 0) (eval (comint-redirect-results-list "\\" ".*" 0) nil) (eval-expression (comint-redirect-results-list "\\" ".*" 0) nil nil 127) (funcall-interactively eval-expression (comint-redirect-results-list "\\" ".*" 0) nil nil 127) (call-interactively eval-expression nil nil) (command-execute eval-expression) Patch attached.
