Bug ID: 67538
Summary: ICE with invalid source allocation
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: mrestelli at gmail dot com
Target Milestone: ---
The following code is invalid since the array dimension is missing,
but since it is an ICE I am reporting it.
$ gfortran --version
GNU Fortran (GCC) 6.0.0 20150910 (experimental)
$ gfortran -c ice.f90
