[vtkusers] EXC_BAD_ACCESS While Running Application Compiled with VTK 5.6.0 on MacOS 10.6.3

[Don Bigler]

All,
	I've encountered a segmentation fault while running an application compiled with VTK 5.6.0 on Mac OS 10.6.3 with XCode 3.2.2.  The non-default VTK build specifications were as follows (using CMake 2.8.1):
CMAKE_OSX_ARCHITECTURES x86_64
CMAKE_OSX_DEPLOYMENT_TARGET 10.6
VTK_WRAP_TCL ON

The initial segmentation fault occurred doing a Release build.  Recompiling to Debug build and running the debugger in XCode, I get an EXC_BAD_ACCESS error message with the following trace (starting with VTK calls):
vtkTextActor::New() -> vtkTextActor::vtkTextActor()
vtkPolyData::New() -> vtkPolyData::vtkPolyData() (line 49 in vtkTextActor.cxx)
vtkDataObject::DATA_EXTENT_TYPE() (line 67 in vtkPolyData.cxx)
vtkInformationIntegerKey::vtkInformationIntegerKey()
vtkCommonInformationKeyManager::Register()
vtkCommonInformationKeyManagerKeys->push_back()
stl_vector.h (line 602):
if(this->_M_impl._M_finish != this->_M_impl._M_end_of_storage)

I'm typically good at tracking these sort of problems down myself.  However, it's not often that my trace ends up in stl_vector.h, usually it's my own error further up in the function calls.  Any of you experts out there have any idea why I'm getting an EXC_BAD_ACCESS message inside a std::vector?  I would not suspect a simple call to vtkTextActor::New() would cause this unless I'm missing something critical.
Thanks,
Don Bigler
