I want to use heightmap created by myself in gazebo, and I`ve followed tutorials like [this one](https://www.vimeo.com/58409707) and [this](https://github.com/MatthewVerbryke/gazebo_terrain). I use Ubuntu 16.04 and gazebo 7 as the second tutorial requires.
At first , I created a heightmap as the first tutorial instructed, and I tested with my gazebo. It worked out, though occasionally the heightmap wasn't loaded fully . Only half of the terrain was loaded, and the other half was flat.
But after a few hours I tried again. But no matter how I try , my gazebo always crashes after I insert heightmap.
And the error msg is always the same:
gzclient: /usr/include/boost/smart_ptr/shared_ptr.hpp:648: typename boost::detail::sp_member_access::type boost::shared_ptr::operator->() const [with T = gazebo::msgs::Response; typename boost::detail::sp_member_access::type = gazebo::msgs::Response*]: Assertion `px != 0' failed.
I've checked a [question](http://answers.gazebosim.org/question/16319/gazebo-700-crash-on-heightmap-insertion/) asked by others before, but is there any better solution to this problem?
Thanks in advance.
