[dune-pdelab] Run-time errors from the gcc sanitizer

[Oliver Sander]

Dear dune-pdelab team,

I tried running my program du jour with -fsanitize-undefined and gcc 4.9.
It spits out the following errors:

/home/sander/dune/dune-pdelab/dune/pdelab/ordering/localorderingbase.hh:20:11: runtime error: load of value 176, which is not a valid value for type 'bool'
/home/sander/dune/dune-pdelab/dune/pdelab/ordering/localorderingbase.hh:20:11: runtime error: load of value 196, which is not a valid value for type 'bool'
/home/sander/dune/dune-pdelab/dune/pdelab/ordering/orderingbase.hh:21:11: runtime error: load of value 207, which is not a valid value for type 'bool'
/home/sander/dune/dune-pdelab/dune/pdelab/ordering/orderingbase.hh:21:11: runtime error: load of value 112, which is not a valid value for type 'bool'

The exact values change with every new run of the program.  valgrind remains silent.

The given line numbers do not give any useful information (to me).

Is that something I should worry about?  Would you be interested in a small test program?

Cheers,
Oliver
