Why does object creation give segmentation fault in DLL?

[Tolga Cakiroglu]

I have written a DLL file in Linux (x86_64). It is as below:

File: lib.dll
=====================
class A{}

extern(C) void foo(){
	Object obj = new Object();   // test 1

	A objA = new A();  // test 2

	char[] c = new char[ 1024 ];   // test 3
}


Compilation code is below:
	dmd -c lib.d -fPIC -debug
	gcc --shared lib.o -o lib.so


Output of programme is like that:
library is loaded now
foo() function is found
unloading libdll.so
Segmentation fault (core dumped)


Situation is that if either only the `test 1` or `test 3` code is 
available in the function, there is no error at all. But once I 
use `test 2` code, it starts giving segmentation fault. Please 
notice that both `test 1` and `test 2` are creating an object 
already. And all of them allocates memory with `new` keyword. But 
only the `test 2` fails. Why is this happening?
