realloc(): invalid pointer (Cyclone DDS)

[knickels]

Operating System:
Description: Ubuntu 18.04.4 LTS
(same result in docker and native)

Installation type:
melodic binaries, eloquent binaries, ros1_bridge source

Version or commit hash:
On eloquent branch of ros1_bridge:
± git rev-parse HEAD
60f903c

DDS implementation:
rmw_cyclonedds_cpp (works with Fast-RTPS)

Client library (if applicable):
rclpy, rospy

Steps to reproduce issue

Shell A:

sudo apt install ros-eloquent-*cyclone*
export RMW_IMPLEMENTATION=rmw_cyclonedds_cpp
mkdir -p ros1_bridge_ws/src
cd ros1_bridge_ws/src
git clone git@github.com:ros2/ros1_bridge.git
cd ros1_bridge
git checkout eloquent
cd ../..
colcon build --symlink-install --cmake-force-configure --cmake-args -DCMAKE_BUILD_TYPE=Debug
ros2 run ros1_bridge dynamic_bridge

Shell B:

. /opt/ros/melodic/setup.bash
roscore

Shell C:

. /opt/ros/melodic/setup.bash
rosrun rospy_tutorials talker

Shell D:

. /opt/ros/eloquent/setup.bash
export RMW_IMPLEMENTATION=rmw_cyclonedds_cpp
ros2 run demo_nodes_py listener

Expected behavior

[INFO] [1583870956.099600]: hello world 1583870956.1 (on Shell C)
[INFO] [listener]: I heard: [hello world 1583870955.1] (on Shell D)

Actual behavior

Shell A:

created 1to2 bridge for topic '/chatter' with ROS 1 type 'std_msgs/String' and ROS 2 type 'std_msgs/msg/String'
[INFO] [ros_bridge]: Passing message from ROS 1 std_msgs/String to ROS 2 std_msgs/msg/String (showing msg only once per type)
realloc(): invalid pointer

Shell D hears exactly one message.

Additional information

Backtrace:

created 2to1 bridge for topic '/rosout' with ROS 2 type 'rcl_interfaces/msg/Log' and ROS 1 type 'rosgraph_msgs/Log'
created 1to2 bridge for topic '/chatter' with ROS 1 type 'std_msgs/String' and ROS 2 type 'std_msgs/msg/String'

This seems to be a duplicate of ros2/rmw_cyclonedds#72. You will need to build CycloneDDS from source until the fix is backported to Eloquent.
