No, the following works fine:
$ curl -v -k  -X POST --data-binary @test https://127.0.0.1:4443/cgi-bin/test.cgi


I put fprintf(stderr, " write %d %d\n", r, space[i].iov_len); 
next line to SSL_write in bufferevent_openssl.c and see:

$ ./test
new POST request
 write 33 33
 write 17 17
 write 24 24
 write 27 27
 write 2 2
 write -1 104857600
<hang until timeout here>

Then I made a hack:

diff --git a/bufferevent_openssl.c b/bufferevent_openssl.c
index 5f98981..36c8625 100644
--- a/bufferevent_openssl.c
+++ b/bufferevent_openssl.c

                                                return -1;
                                bev_ssl->last_write = space[i].iov_len;
+                               blocked = 1;
                                break;
                        default:
                                conn_closed(bev_ssl, BEV_EVENT_WRITING, err, r);
                                bev_ssl->last_write = -1;
+                               blocked = 1;
                                break;
                        }
-                       blocked = 1;
                        break;
                }
        }

All works fine now.
