[Oisf-devel] Building suricata 1.4.2 with clang

[Sebastian Roschke]

Dear list,

not sure if I should direct this request somewhere else. I am trying to
build suricata with clang and ASAN:

CC=clang CFLAGS='-O0 -g -fsanitize=address' CPPFLAGS='-O0 -g
-fsanitize=address' ./configure
make

This works fine. Running suricata afterwards miserably fails:

./suricata -c suricata.yaml
6/6/2013 -- 21:19:50 - <Info> - This is Suricata version 1.4.2 RELEASE
6/6/2013 -- 21:19:50 - <Info> - CPUs/cores online: 4
