after upgrading my system to Debian/Jessie,
I get a segfault in gdb, on attempt to launch the test-suite.
By reducing the modules linked into the test-suite, I could
narrow down the problematic code. It should be noted though,
that this code is not the only problematic object, rather it
is one of several ways to make gdb crash. I picked this example,
as it is rather recent code and lookes fairly straight forward.
Next step was to extract the first segment of the unit test
and plant it into a simple executable with a main function
and without any fancy loading of dynamic libraries.
So it turns out that shared object loading is *not* involved.
But some "interesting" new C++11 constructs are involved,
like passing a local function-ref into a lambda, which later
on will be wrapped into a Lumiera Iterator and then evaluated
through a range-for-loop. Sounds interesting
