Error loading URDF malloc:() memory corruption

[Minerva Vargas]

Hi,

I am new to MoveIt! I'm trying to load a URDF I generated from a XACRO file into moveit_setup_assistant. However, while loading the file the process aborts:

 [ INFO] [1461143745.638481523]: Loaded boxy_description robot model.

[ INFO] [1461143745.638655255]: Setting Param Server with Robot Description

*** Error in `/opt/ros/indigo/lib/moveit_setup_assistant/moveit_setup_assistant': malloc(): memory corruption: 0x00000000021ed6b0 ***

Aborted (core dumped)

Does anyone knnows what does this malloc(): memory corruption means? 

I can load other URDFs without problem.

Can you send the generated URDF so that we can reproduce the problem?

Do other ROS tools that use URDF give a similar error? e.g. "check_urdf (your urdf file)" is a good basic checks which is provided by the system package liburdfdom-dev.

The error message means that the program failed to allocate dynamic memory because the address is tried to allocate to became invalid. It's probably due to a memory error somewhere in MoveIt or the URDF parser.

Attached is the URDF

Thanks!

Aparently, the error was caused by the STL files I was using for the robot. 

The STLs made with Inventor 2016 generate some problems with MoveIt!, the easiest solution was  transformint the STL to STL using ctmconv, this changes the headers and footers of the files to something MoveIt! can work with.
