Disabling GC solved this problem. I think only this
  Data_Wrap_Struct(rb_cObject, 0, 0, setting)
place of code can be buggy.
I passed NULL to "free" parameter because I do not allocate memory for
setting structure and do not free it (not sure what will be if it is
freed by library, probably I need to make some checks). What do I need
to pass as destructor in this case?
