Consider: import std.stdio; struct S1 { this(int) { writeln("constructed"); } ~this() { writeln("destroyed"); } } struct S2 { this(int) { throw new Exception("a"); } } void fun(S1, S2, S1) {} void main() { fun(S1(2), S2(2), S1(2)); } Running this code will create an object of type S1 that is never destroyed. This is somewhat related to http://d.puremagic.com/issues/show_bug.cgi?id=9704, just there's no postblit.

I think this can be marked as a dup because it is a particular situation of essentially the same case described in issue 9704.

This indeed a more generically worded description, but essentially, the same thing. Also, (since links never hurt), this issue was also discussed recently in learn: http://forum.dlang.org/thread/20130628005448.00000969@unknown?page=2 *** This issue has been marked as a duplicate of issue 9704 ***
