If you can still reproduce it, please show the data which is involved
in the segfault:
(gdb) frame 0
(gdb) p w->desired_matrix
(gdb) p w->desired_matrix->nrows
(gdb) p window_wants_tab_line (w)
(gdb) p window_wants_header_line (w)
TBH, I'm quite confused to see that line 3734 segfault, because I
cannot understand how w->desired_matrix can be NULL or bogus.
Thanks.
