--- Comment #7 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
Well, I can confirm this. Output from valgrind shows as the first error:

So, it is a finalizer problem. The allocate statement was at
function process_component_extract_mci_template (component) &
result (mci_template)
class(mci_t), allocatable :: mci_template
class(process_component_t), intent(in) :: component
if (allocated (component%mci_template)) &
allocate (mci_template, source = component%mci_template)
end function process_component_extract_mci_template
Hopefully, this can narrow things down a bit.
