Right, thanks for the notice.  And, my debugging of this lead to quite similar
patch and that is pretty much what ipa-pure-const.c does too.

File that triggers the ICE

The following code leads to internal compiler error with the message:

$ gfortran -c muli_trapezium.f90
muli_trapezium.f90:139:0:

             (node%get_d_value() / 2 - node%get_r_value_array ()))

muli_trapezium.f90:139:0: internal compiler error: Abort trap: 6
gfortran: internal compiler error: Abort trap: 6 (program f951)

I'm using gcc 5.0 (svn revision 220505).
