commit 6208547002b4d897c14364661ca4e2e5d0b80006
Author: Daniel Stenberg <address@hidden>
AuthorDate: Sun Jun 18 17:54:55 2017 +0200

    PIPELINING_SERVER_BL: cleanup the internal list use
    
    The list was freed incorrectly since the llist refactor of
    cbae73e1dd959. Added test 1550 to verify that it works and avoid future
    regressions.
    
    Reported-by: Pascal Terjan
    
    Fixes #1584
    Closes #1585
