using new in shared library causes access violation

[dd0s via Digitalmars-d-learn]

hi,

I have a c++ program with a plugin system and i try to write a 
plugin for it.
when the plugin is loaded by the program the extern (C) int 
OnInit() method is called. so far everything works fine. But as 
soon as i try to create a new class instance a segmentation fault 
occurs ( the constructor is empty ).

Here is a screenshot with all the important code
# error message in the left console
# right top the executed code
# right bottom the dub.json i use

thank you for helping
