Thank you for the solution. I removed the * before
login_context and it works fine. Now there is an
other problem. I put this piece of code in an existing
application(.c file) and it failed. I mean that this
code can run stand alone, but not as part of some
other file. Please help me to fix it.
By the way, the stack trace is below:
