Segfault during soft-stop

[Apollon Oikonomopoulos]

Hi all,

Current master segfaults during soft-stop with the following config:

  global
      log /dev/log    local0
  
  frontend test
      mode http
      bind 127.0.0.1:8888
      bind ::1:8888
      redirect prefix http://example.com 
  
gdb shows:

 Program received signal SIGUSR1, User defined signal 1.
 [WARNING] 106/123715 (18187) : Stopping frontend test in 0 ms.
 
 Program received signal SIGSEGV, Segmentation fault.
