>Description:
"gcc -Wall x.cpp" prints this error message:

x.cpp: In function `void freeclass(class_1 *)':
x.cpp:20: Internal compiler error 980605.
x.cpp:20: Please submit a full bug report.
x.cpp:20: See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.

>How-To-Repeat:
#include <stdlib.h>

class class_1 {
  public:
    class_1(void) {};
    virtual ~class_1(void) {};
};

template<class Type> class class_2 {
  public:
    class_2(void) {};
    virtual ~class_2(void) {};
};

void freeclass(class_1 *p)
{
  if (p) {
  
    // Internal compiler error 980605:
    p->~class_2();

    // correct:
    // p->~class_1();

    // correct error message:
    // p->~class_2<int>();

    free(p);
  }
}

int main(void)
{
  class_1 v1;
  class_2<int> v2;
  // same error:
  // v1.~class_2();
  return(0);
}
