Re: c++ 2.95.2: goto+dtor bug

Hi

This bug also exists in the current CVS as of 12th Feb.

Here are a couple of modified versions of 
the original test case which show that its
only some destructors which don't get called.

---------------------------------------------------
#include <stdio.h>
class a
{
private:
   int n;
public:
   a(int x)  { n = x; printf("ctor %d\n", n); }
   ~a()      {        printf("dtor %d\n", n); }
};
int main(int argc,char **argv)
{
   a var0(0);
   if(argc>1)
   {
   leave:
      return 0;
   }
   a var1(1);
   a var2(2);
   goto leave;
}
---------------------------------------------------
Here's the output

ctor 0
ctor 1
ctor 2
dtor 2
dtor 0

---------------------------------------------------
#include <stdio.h>
class a
{
private:
   int n;
public:
   a(int x)  { n = x; printf("ctor %d\n", n); }
   ~a()      {        printf("dtor %d\n", n); }
};
int main(int argc,char **)
{
   a var0(0);
   if(argc>1)
     {
leave:
      return 0;
     }
   a var1(1);
   a var2(2);
   if (argc>1)
      {
leave2:
       goto leave;
      }
   a var3(3);
   a var4(4);      
   goto leave2;
}
---------------------------------------------------
Here's the output

ctor 0
ctor 1
ctor 2
ctor 3
ctor 4
dtor 4
dtor 2
dtor 0
