--- Comment #3 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
Grepping the list of 'note:' in our build process, it triggers for at least
these functions:

_gfortran_matmul_r8
_gfortran_reshape_4
_gfortran_reshape_c4
_gfortran_reshape_c8
_gfortran_reshape_r4
_gfortran_reshape_r8
_gfortran_unpack1

so it is somewhat general.
