[Insight-developers] WrapITK + Tcl -- still having a crash with itk::Vector

[kent williams]

I will be at neither. I think my boss Hans Johnson will be at one or the
other.

As it turns out I did some more testing. It is failing on OS X 10.6 with the
XCode 3.2.2 compilers.  It isn't failing on RHEL 5.5.

The OS X uses gcc 4.2.1 RHEL is using 4.1.2.

The problem occurs in <builddir>/Wrapping/WrapITK/SwigRuntime/swigrunTcl.cxx
in (on my systems) line 738 in SWIG_Tcl_GetArgs:

    vptr = va_arg(ap,void *);

SWIG_Tcl_GetArgs steps through a variable argument list, in order to pick up
arguments and store them so that _wrap_itkFixedArrayD3_SetElement can call
SetElement on the vector.

On RHEL5, 64-bit, the va_arg macro correctly steps through the arguments on
the stack.  On OS X, it gets the first 2 arguments -- apparently -- correct,
but then returns 0x100000000 for the third arg.  Then on line 780 it tries
to use this as a pointer, and you get a crash.
