I need to see what's in the buffer and some other variables. These
are for the call-stack frame inside display_line:
(gdb) p current_buffer->text->beg
(gdb) p it->current
(gdb) p it->w->desired_matrix->nrows
(gdb) p MATRIX_ROW_VPOS(row, it->w->desired_matrix)
(gdb) thread apply all bt
(gdb) xbacktrace
And finally, any idea what you were doing when this happened?
Thanks.
