Source:
#include <iostream.h>
class foo {public:  static bar() { cout << "bar ";}  foo() {cout << =
"ctor ";}  ~foo() {cout << "dtor\n";}};
void main(){  foo().bar();}
Output
bar dtor
Destructor was called without calling the constructor. This was reported =
in
Windows Development Journal with comments by Ron Burk years ago and
now I think only DMC++ still has this bug.

GNU saying "bar" - perhaps the optimisation is too wonderful to be =
true...

VC++ and BCC32 says "ctor bar dtor" which object was created and =
destroyed.=20

Does Ron have a web page for this (i.e. are there other tests of =
interest?)?

Unfortunately Ron has left WDJ and WDJ is now called wd-mag and I =
stopped
my subscriptions because the journal is bad now.

The file date of the source sayd 4th December 1995 so the bug is really =
really old.

I'll try to dig the article out from my boxes from home and forward it =
you.

Cheers...
