Bug ID: 85102
Summary: ICE in gfc_conv_intrinsic_dot_product, at
fortran/trans-intrinsic.c:4464
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Follow-up of pr83998, but gives an ICE down to at least 4.8 :
$ cat z1.f90
program p
integer, parameter :: a((2)) = 1
integer, parameter :: b = dot_product(a, a)
print *, b
end
$ cat z2.f90
program p
integer, parameter :: a((0)) = 1
integer, parameter :: b = dot_product(a, a)
print *, b
end
$ gfortran-8-20180325 -c z1.f90
z1.f90:4:0:
print *, b
