Description Risto Saarelma 2010-09-26 00:52:15 UTC 
Tried to build the following on 64-bit Linux with DMD v2.049:

----
import std.container;
 
struct X {
  int a;
}
 
void main() {
  auto c = Array!X();
}
----

I get this error message:
src/phobos/std/container.d(1485): Error: template instance template 'hasElabo
rateDestructor' is not defined                                                                     
src/phobos/std/container.d(1485): Error: hasElaborateDestructor!(X) is not an
 expression

It looks like hasElaborateDestructor is not defined anywhere in the source tree.

i can confirm this does not work under win32 either. what is the use of a container that one cannot store user defined types in ? and where is the missing hasElaborateDestructor template ?
