Bug ID: 77381
Summary: ICE in resolve_equivalence, at fortran/resolve.c:15149
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gerhard.steinmetz.fort...@t-online.de
Target Milestone: ---
For versions down to at least 4.8 :
$ cat z1.f90
module m
character(3) :: a(2), b(2)
equivalence (a(2)(1:2), b(1)(2:3))
end
program p
use m
end
$ cat z2.f90
module m
character(3) :: a(2), b(2)
equivalence (a(2)(1:3), b(1)(1:3))
end
program p
use m
end
$ cat z3.f90 ## similar to z2.f90, no ICE
module m
character(3) :: a(2), b(2)
equivalence (a(2)(:), b(1)(:))
end
program p
use m
end
