- You connect signal/slot after sending the post message
- onReply() is not a slot
- You use QNetworkAccessManager before running the event loop (app.exec())
I'm not certain these issues are enough to produce a crash, but fixing them could help. In general it would be OK to just move you network handling code to a separate class (QObject subclass) and handle operations there, after event loop is started.

The same result occur, when I wrap network part in a class.
