[Bug middle-end/40980] New: air.f90 ICEs compiler with -fgraphite-identity

[howarth at nitro dot med dot uc dot edu]

When the Polyhedron 2005 benchmark air.f90 is compiled with
-fgraphite-identity, the compiler ICEs with the error...

gfortran -O2 -fgraphite-identity air.f90 -o air
air.f90: In function ‘spectop’:
air.f90:1064:0: error: Incompatible types in PHI argument 0
character(kind=4)

integer(kind=4)

ivtmp.1799_745 = PHI <var.1825_744(157), D.2584_20(158)>

air.f90:1064:0: internal compiler error: verify_stmts failed
