[Bug fortran/35780] New: internal compiler error for complicated PARAMETER expressions

The following little module causes an ICE.  I believe the bigger module
following it causes different ICE's, or perhaps more instances of the
same one.  But, things move around for me when I try to isolate
statements and I can't be sure.  My advice would be to fix this one 
and hope some magic happens to the other module.

! try this after you've fixed the two related problems.
! this is the full version of the parameters that spawned
! the smaller reports.  The ICE moved around and came and
! went as I tried to isolate things.  

! I believe there are two more ICEs in this set, but they're
! hard to isolate when things move around.
