Here's the smallest part of subr-x which causes the crash: ;;; subr-x.el --- extra Lisp functions -*- lexical-binding:t -*- (defun internal--build-bindings (bindings) "Check and build conditional value forms for BINDINGS." (let ((prev-var t)) (mapcar (lambda (binding) (let ((binding (internal--build-binding binding prev-var))) (setq prev-var (car binding)) binding)) bindings))) Interestingly, if I remove the first line, there's no crash. So lexical-binding has something to do with this. I cannot see what could trigger the crash. The fact that 'binding' is used both as an argument and as the variable which is bound to the return value, perhaps? Let me know if you want the C reproducer for this minimal file. Thanks.
