Bug 6223 – Crash on exit when embeeding std.stream.File in a class.

The following piece of code seems to crash consistently on Windows (but it seems to also affect Linux, and that's where I found it - particularly, it only seemed to crash depending on the content of a static constructor: removing almost any line from it removed the crash; the minimal test case was large, so I have not included it). import std.stream; import std.stdio; class X { Stream output; this(Stream output) { this.output = output; } void close() { output.close(); } ~this() { close(); } } int main(string[] args) { new X(new std.stream.File("x.log", FileMode.OutNew)); return 0; } Adding "writeln(output.isOpen);" to the close() method removes the crash (and returns true before .close() and false after .close(), as one would expect). On the large test case for Linux, however, the crash persisted even with isOpen(), and just "touching" the object crashed the program (it looked like I was working with an already released object). PS: Sorry if I'm missing something obvious and this is a not a bug, but the behaviour is odd, at least. Also, I posted a message directly to the mailing list - I found that bugzilla.digitalmars.com was only for DMC, so I thought that I should use the mailing list for D directory - sorry!
