By adding a destructor to main class to example in the bug 21228
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21228) will produce incorrect
warning about code that "will never be executed"

# g++  -Wunreachable-code gstest.cpp
gstest.cpp: In constructor ‘testString::testString()’:
gstest.cpp:24: warning: will never be executed
gstest.cpp: In constructor ‘testString::testString()’:
gstest.cpp:24: warning: will never be executed

#cat gstest.cpp
// #include <stdio.h>

class testStringBase
{
public:
  ~testStringBase();
  char *stringPtr;
};

testStringBase::~testStringBase()
{
  stringPtr = 0;
}

class testString : public testStringBase
{
public:
  testString();
};

testString::testString()
{
  stringPtr = (char *) 9;
}

int main(int argc, char **argv) {
  testString s;
  //  printf("s.stringPtr is %ld\n", (unsigned long) s.stringPtr);
}
