compatibility of qt4.8.2 with qt 5.1.1

[ntl]

we are using "push_back" command in qt 4.8.2 for storing the different elements in an array. but the same thing we are running in the qt 5.1.1 version.but it is showing the error ".exe exited with code -1073741819". suggest the commands like push_back in the qt 5.1.1

push_back on what?

Since you have a crash, analyze the backtrace of the crash.

You are clearly on Windows. Your error number is 0xC0000005 (http://stackoverflow.com/questions/5303524/what-exactly-is-the-scope-of-access-violation-0xc0000005) in hex. Access violations from developer code are usually the result of using an uninitialised or invalid pointer. That it didn't crash (not the same as worked) in Qt4 is probably dumb luck (or less protective compiler output).
