I am having problems debugging structs passed as parameters with GDB 4.6.
I am using a Sun 4/280 running SunOS 4.1.1.  I am compiling my code with
GCC 2.2.2.  The main thing is that GDB shows the wrong values for the
struct contents, but there are other anomalies, such as segmentation
faults when I call functions in the program being debugged that take
structs as arguments.  Enclosed below is some trivial test code that
triggers the problem.

Is this a known problem?  I've looked in both the GDB and GCC source
distributions to see if it is documented.  Is there a workaround?  Is this
an incompatibility with GCC 2.2.2?  Help!

If you reply to this message, please send a copy to my address by e-mail.

  for (i = 0; i < 8; i++)
    printf ("%c\n", w._[i]);
