Also install haproxy-dbgsym. You need to comment the chroot directive in
your HAProxy configuration if it's enabled. Also, you need to set the
core pattern to a fixed directory where haproxy user can write to, like:
sysctl -w kernel.core_pattern=/tmp/core.%p
Then, on next segfault, you should get your coredump.
