[ http://issues.apache.org/jira/browse/STDCXX-179?page=all ] Martin Sebor reassigned STDCXX-179: ----------------------------------- Assign To: Martin Sebor > Inserting a Vector into a Vector Corrupts Vector Data > ----------------------------------------------------- > > Key: STDCXX-179 > URL: http://issues.apache.org/jira/browse/STDCXX-179 > Project: C++ Standard Library > Type: Bug > Components: 23. Containers > Versions: 4.1.3 > Environment: All operating systems > Reporter: Craig Chariton > Assignee: Martin Sebor > Priority: Critical > > There is an interesting problem that occurs with vectors. Here is the sample code: > #include // for cout, endl > #include // for vector > int main () > { > std::vector a; > a.push_back(1); > a.push_back(2); > a.push_back(3); > a.push_back(4); > std::vector b; > b.push_back(0); > a.insert(a.begin(), b.begin(), b.end()); > for( std::vector::iterator i = a.begin(); i != a.end(); ++i) > std::cout << (*i) << ","; > std::cout << std::endl; > return 0; > } > The output is 0,2,3,1,2, instead of 0,1,2,3,4, . > I tried some other combinations as follows: > a = 1, b = 0 - works, get 0,1 > a = 1,2, b = 0 - works, get 0,1,2 > a = 1,2,3, b = 0 - fails, get 0,2,1,2 > a = 1,2,3, b = 0, 5 - fails, get 0,5,3,2,3 > a = 1,2, b = 0,5 - works, get 0,5,1,2 > a = 1,2,3,4, b = 0,5 - works, get 0,5,1,2,3,4 > a = 1,2,3,4,5, b = 0,5 - fails, get 0,5,3,1,2,3,5 -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
