Started to ICE with gfortran-7 :
(derived from a valid z0.f90)
$ cat z0.f90
program p
integer, allocatable :: a[:]
print *, allocated(a)
end
$ cat z1.f90
program p
integer, allocatable :: a[:]
print *, allocated(a[1])
end
$ cat z2.f90
program p
integer, allocatable :: a[:]
if ( allocated(a[1]) ) stop
end
$ gfortran-10-20200216 -c z1.f90 -fcoarray=single
