--- Comment #4 from Tom <tom.k.cook at gmail dot com> ---
This bug appears to be in the GFortran 5.3.1 released in Ubuntu 16.04, where it
manifests as:

       A_WVSTR%rSurface = 0.0
   1
  internal compiler error: in wide_int_to_tree, at tree.c:1464

A_WVSTR is a function parameter, rSurface is a 3-dimensional allocatable array
of real(kind=4).  Apologies that I am unable to provide full source for the
offending module.

Is there a known work-around that can be used in the source that triggers this
problem?  We build the same source with a GFortran 5.3.0 which we built
ourselves without problems.

Regards,
Tom
