[omniORB] omniORBpy: segfault/bus errors using Any?

[Mark Borges]

I'm not sure if this is an obscure compiler/optimization bug, a
misunderstanding of the Python mapping for Any on my part, or
something else entirely different.

Running the following snippet of code (which is boiled down from a
larger application and basically nonsensical as-is) I consistently get
a segmentation fault:

-----------------------------------------------------------------------
$ ./srv.py &
IOR:000000000000001049444c3a592f5265706c793a312e300000000001000000000000002c000100000000000f3134312e3230342e3137382e3638000299e100000000000c38572cf3a7abb22b00000002

$ ./clt.py
xx= PENDING
typecode= <omniORB.CORBA.TypeCode instance at 12bea8>
<method Any.typecode of Any instance at 12bec0>
{'dueDate': '01/01/2000', 'woState': PENDING, 'woId': '12345'}
zsh: 16940 segmentation fault (core dumped)  ./clt.py
-----------------------------------------------------------------------

Can anyone verify if this is reproducible elsewhere, or if I should
focus more on the local installation of omniORBpy and the specific
build I'm using on this OS:

  $ gcc -dumpversion -dumpmachine
  2.95.2
  $ gcc -dumpmachine 
  sparc-sun-solaris2.6
  $ uname -a
  SunOS jimi 5.6 Generic_105181-14 sun4u sparc SUNW,Ultra-5_10

Or if I've done something boneheaded in the appended code?

-----------------------------------------------------------------------
$ cat Y.idl
module Y {

  enum jobState {
    PENDING,
    COMPLETED
  };

  struct Foo {
    string woId;
    jobState woState;
    string dueDate;
  };

  interface Reply {
    oneway void result (in unsigned long id,
                        in boolean success,
                        in any data);
  }; //end of interface
}; // end of module
