[...] I am a C newbie. I was playing around with editfns.c that would implement RMS's (message t ..) idea.. , and tried the attached patch. It seemed to compile fine. But, compiling via 'make bootstrap' always fails at the end with a segfault, as seen below. If I revert to the original editfns.c, 'make bootstrap' finishes all the way to the end. Any hints what I am doing wrong? Thanks. Loading loadup.el (source)... (/home/deego/emacscvs-anon/emacs/lisp) Loading emacs-lisp/byte-run... Loading emacs-lisp/backquote... Loading subr...
