[omniORB] SIGSEGV in marshalPyObjectWChar

[Joel Wagner]

While using omniORB-4.0.3 and omniORBpy-2.3 on a Linux RHAS 2.1 machine I'm
experiencing a crash in the marshalling code of omniORBpy.  Any suggestions
on how to get through this problem would be greatly appreciated.

Thanks,

Joel


Here is an excerpt from the Python script that causes the problem.

	m = V.M.Create_Args
	m.Key = 0
	m.Label = u'x' * 65
	resp, out = session.Create([m], 0)

Here is the corresponding IDL:

	struct Create_Args
	{
	    long                                    Key;
	    wchar                                  Label[  65];
	} ;

	typedef sequence<Create_Args> Create_Args_Seq ;

	unsigned long CreateMedia( inout Create_Args_Seq Arguments, in
unsigned long Flags) ;


Here is the stack trace:
