Barry Alan Scott [EMAIL PROTECTED] added the comment:
You are right that its the Py::Long( Py::Float( double( x ) ) )
that is triggering this problem.
Here is the gdb from the powerpc build that shows the
info you asked for and show res being corrupt.
I'm going to try and build a smaller version of this
problem using a minimal PyCXX module.
