Comment(by asn):

 I wonder how:
 {{{
 if (down->buffer != bev) {
     conn_free(down);
     return;
 }
 }}}
 in the top of `downstream_read_cb()`, would act as an anti-crash temporary
 workaround.

 `conn_free(down);` might make it too much undefined behavior, maybe just
 returning and suffering the memory leak could also work.

 Messy, but it might do it for the weekend.
