Sorry for the late reply!

cursor (before do) = 0x0
* GPT_BYTE = 3072
* GAP_SIZE = 2000
* BEG_ADDR = 0x0
* current_buffer->text->beg = 0x0

cursor (before memchr) = 0x0
* GPT_BYTE = 3072
* GAP_SIZE = 2000
* BEG_ADDR = 0x0
* current_buffer->text->beg = 0x0


BTW, I think I found a reproducible recipe: 

1. after starting dirvish, C-x 0 repeatedly to delete all windows (mode line still shows “name|mtime”)
2. C-x k to kill the buffer
3. Dirvish automatically restarts itself, and this time the mode line shows nothing
4. C-x k to kill the buffer, and emacs crashes
