Error description
The compiler is issuing an unexpected error message when using TR1 extensions for the following test case: ===== TESTCASE: $ cat test.cpp #include <memory> int main() { std::tr1::shared_ptr<int const> ptr; if (ptr) {} return 0; } ===== ACTUAL OUTPUT: $xlC test.cpp -D__IBMCPP_TR1__ "/usr/vacpp/include/memory", line 850.34: 1540-0258 (S) A return value of type "void *" cannot be initialized with an expression of type "const int *". "usr/vacpp/include/memory", line 848.9: 1540-0700 (I) The previous message was produced while processing "std::tr1::shared_ptr<const int>::operator void *() const". "test.cpp", line 4.13: 1540-0700 (I) The previous message was produced while processing "main()". ===== EXPECTED OUTPUT: Should compile clean
Local fix
int main(void) { shared_ptr<int const > ptr; // changing this to <int const *> // works fine if (ptr) {} // or changing this to if(&ptr) works fine return 0; }
Problem summary
This problem is specific to tr1::shared_ptr There are cases where an object of this class could not be used in a condition such as if(myptr){}
Problem conclusion
The library class has been updated to allow this.
Temporary fix
