But the phenomenon seems to be VERY similar. So if you are confident
with some changing the sources you might try to do the following: remove
the deconstructor of library_init: in ex.h put comments in front of
~library_init and in utils.cpp put comments in front the definition of
~library_init (approx. lines 395-403) and recompile.
Maybe the seg fault is gone then.
