From 6208547002b4d897c14364661ca4e2e5d0b80006 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Sun, 18 Jun 2017 17:54:55 +0200 Subject: 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.
