>Description:
For the initialization of the static array in the program
below, we generate calls to the class destructor, but there
are no corresponding calls to the constructor.
This is what i get when i run this program:
$ g++ -o x x.cc
$ ./x
dtor 804973c
$
If i change the program so that Cls is not a template class,
then it executes correctly.
>How-To-Repeat:
------------------------
extern "C" int printf (const char*, ...);
template <class T>
struct Cls
{
Cls () { printf ("ctor %x\n", this); }
~Cls () { printf ("dtor %x\n", this); }
};
static Cls<int> xxx[1];
int main ()
{
return 0;
}
