Hi Dave --
It looks like my argv[argc] is not NULL (see below), so are we getting that
this problem is boost::python's fault?
Thanks!
Amos.
Looking in the boost code, I see this is how MPI_Init is called:
environment::environment(int& argc, char** &argv, bool abort_on_exception)
: i_initialized(false),
abort_on_exception(abort_on_exception)
{
if (!initialized()) {
BOOST_MPI_CHECK_RESULT(MPI_Init, (&argc, &argv));
i_initialized = true;
}
MPI_Errhandler_set(MPI_COMM_WORLD, MPI_ERRORS_RETURN);
}
Getting some more info from a gdb session (the trace is the same):
(gdb) up
