C++ interface example outputs "double free or corruption (out)"

[victor-kowalski-m]

Hello,

I tried to execute the provided C++ interface example code and it outputs:

double free or corruption (out)
Aborted (core dumped)

I recompiled the code with the flag -fsanitize=address and re-executed it, it outputs:

The basic C interface example works, but if I create a variable such as an Eigen::Matrix inside the code, the same error occurs.

I am running it on an openSUSE 5.14.21 system, using gcc as the compiler.

Is there some sort of memory issue?
