    a debugging question

    I have compiled a program with -g option with gcc, but I am almost
    unable to debug it. For most variables, it does not allow me to print
    their values while debugging. Could someone tell me what compile
    options I have to use or how I should call gdb (if any special flags I
    have to use). I have used gdb a lot a few years ago, and I never had
    this problem.
    It is a small program so today I used the time tested method of
    debugging - add lots of print statements - but I hope someone will
    suggest a better way.
    Thanks.

      Not here, but the people in gnu.g++.help should be able to.

          Yes, somebody in the newsgroup 'gnu.gcc.help' could.

          Somebody in the compiler newsgroup probably will, if you ask.
