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
Is it possible that you already compiled the sources before a "git pull" ?
If so, did you make a "make clean" before compiling ?
make CFLAGS="-O0 -g" TARGET=osx USE_LUA=yes LUA_LIB=/opt/lua/lib

3. copy to /usr/local/bin ( optional )

6. running haproxy :

Segmentation fault: 11
if # http-request lua mirror if debugme is commented then haproxy runs
without problem
haproxy -f lua.conf
