| The summary says it all ;-)
void Fl_Text_Display::wrap_mode(int wrap, int wrapMargin) {
mWrapMargin = wrapMargin;
mContinuousWrap = wrap;
/* wrapping can change change the total number of lines, re-count */
mNBufferLines = count_lines(0, buffer()->length(), true);
---------------------------------^^^^^^^^
I tried to add:
if (!buffer()) return;
before the marked line, but this seemed to prevent the wrap mode from being set correctly, though I'm not sure.
BTW: Fl_Text_Display::wrap_mode() is missing in the documentation

| Addition: To be clear:
(1) Setting wrap_mode() after assigning a text buffer works as expected.
(2) Setting wrap_mode() before assigning a buffer crashes (without a patch).
(3) After patching Fl_Text_Display::wrap_mode() as described above, setting wrap_mode() before text buffer assignment doesn't crash, but doesn't set wrapping as it should (IMHO).
