HI,
trying to test LUA on macosx I am getting segmentation fault
1. get
~/repo/haproxy/haproxy (master)$ git pull
Already up-to-date.
2. compile
make CFLAGS="-O0 -g" TARGET=osx USE_LUA=yes LUA_LIB=/opt/lua/lib
LUA_INC=/opt/lua/include LUA_LIB_NAME=lua
gcc -Iinclude -Iebtree -Wall -O0 -g -DENABLE_POLL -DENABLE_KQUEUE

3. copy to /usr/local/bin ( optional )
mv haproxy haproxy-1.6-dev1-601a4d-55
mv haproxy-1.6-dev1-601a4d-55 /usr/local/bin
