Eigen Assertion Error in future collision node.

[Vinay545]

The future_collision node is halting with following assertion failure.

eigen_assert((internal::UIntPtr(eigen_unaligned_array_assert_workaround_gcc47(array)) & (15)) == 0
&& "this assertion is explained here: "

Solution :

The airsim (static) libraries are compiled using 3.3.2 version Eigen libraries. And octomap_server(dynamic) libraries are compiled using 3.2.7 version Eigen Libraries.
I have not seen this error.
So, in future_collision executable we are providing eigen library symbols through airsim static libraries i.e., 3.3.2 version. When octomap_server library part is executing, it is supposed to execute 3.2.7 version code, but is executing 3.3.2 version code as the symbols are already resolved.
So we have compiled Airsim libraries using 3.2.7 version of Eigen libraries. The issue got resolved.

If the same issue happens with airsim_img_publisher node, compiler airsim_img_publisher package with 3.3.2 version.
