Running with +edit:

trace:edit:EDIT_MakeFit We now have 63+1
trace:edit:EDIT_EM_ReplaceSel inserting stuff (tl 0, strl 49, selstart 0
((null)), text (null))

In the last log line :

2627         if (strl) {
2628                 /* there is an insertion */
2629                 tl = get_text_length(es);
2630                 TRACE("inserting stuff (tl %d, strl %d, selstart %d (%s),
text %s)\n",
.                          tl, strl, s, debugstr_w(es->text + s),
debugstr_w(es->text));
2631                 for (p = es->text + tl ; p >= es->text + s ; p--)
2632                         p[strl] = p[0];
2633                 for (i = 0 , p = es->text + s ; i < strl ; i++)
2634                         p[i] = lpsz_replace[i];
2635                 if(es->style & ES_UPPERCASE)
2636                         CharUpperBuffW(p, strl);
2637                 else if(es->style & ES_LOWERCASE)
2638                         CharLowerBuffW(p, strl);
2639                 text_buffer_changed(es);
2640         }

At line 2631 p = NULL because es->text = NULL. So the loop comparison will work
and the crash in 2632 is expected.
