I have a Visual Studio 2008 C++03 application where I'm using boost::phoenix::erase (v1.49.0) on a std::list<int> container that does not contain the element I want to erase.
This example is demonstrates the issue:
int main() { namespace bp = boost::phoenix; namespace bpa = boost::phoenix::arg_names;
std::list< int > a;
// works as expected (does nothing) a.erase( a.end(), a.end() );
// fails a debug assertion "list erase iterator outside range" // Microsoft Visual Studio 9.0\VC\include\list\list : 790 bp::erase( bp::ref( a ), a.end() )();
return 0; }
In release mode, this de-references an uninitialized pointer and the application crashes. Am I using boost::phoenix::erase correctly?
Your phoenix code only passes one iter. a.erase(a.end()) is illegal. To get the equivent of your non-phoenix code, you need bp::erase(bp::ref( a ), a.end(), a.end()); In Christ, Steven Watanabe
