--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Confirmed from 4.8 up to trunk (6.0 configured with --enable-checking=release).
When 6.0 is configured with the default value of --enable-checking, the ICE is

internal compiler error: tree check: expected function_type or method_type,
have pointer_type in gimplify_call_expr, at gimplify.c:2391

The ICE with 4.7 is

pr67044.f90: In function 'cont_add':
pr67044.f90:39:0: error: non-function in gimple call
D.1930 = unpck.4 (&D.1900, &D.1901);

pr67044.f90:39: confused by earlier errors, bailing out

and with 4.6

pr67044.f90: In function 'cont_add':
pr67044.f90:49:0: internal compiler error: in cgraph_node, at cgraph.c:495

The code compiles if the line

   allocate( z%f , source=unpck(x)+unpck(y) )

is replaced with

   allocate( z%f , source=unpck(x) )
