# commit f874a83
# BUG/MINOR: lua: Segfaults with wrong usage of types.
#
# Patrick reported that this simple configuration made haproxy segfaults:
#
#     global
#         lua-load /tmp/haproxy.lua
#
#     frontend f1
#         mode http
#         bind :8000
#         default_backend b1
#
#         http-request lua.foo
#
#     backend b1
#         mode http
#         server s1 127.0.0.1:8080
#
# with this '/tmp/haproxy.lua' script:
#
#     core.register_action("foo", { "http-req" }, function(txn)
#         txn.sc:ipmask(txn.f:src(), 24, 112)
#     end)
#
# This is due to missing initialization of the array of arguments
# passed to hlua_lua2arg_check() which makes it enter code with
# corrupted arguments.
#
# Thanks a lot to Patrick Hemmer for having reported this issue.
