[Bonmin] Segfault in simple example

[Paul Lange]

Hello,

I'm trying to use Bonmin but unfortunately have problems with getting a 
simple example to work.

See the code here [1], it's basically a cleaned up version of the 
provided example.
When I run it, I get a segfault like shown below. I tried compiling with 
different versions of gcc. Below is the output from a version compiled 
with clangs address sanitizer.

Any help, ideas or tips are greatly appreciated.

Thanks and best regards,
Paul
