Bug ID: 70068
Summary: ICE: out of memory on involving empty substring
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: [email protected]
Target Milestone: ---
Looks strange, is legal (empty substring, zero length) :
$ cat z1.f90
program p
character(99), parameter :: x(2) = ' '
character(99), parameter :: y = x(2)(99:1)
end
$ gfortran-6 z1.f90
f951: out of memory allocating 18446744073709551232 bytes after a total of
634880 bytes
$ cat z2.f90
program p
character(99), parameter :: x(2) = ' '
character(99) :: y = x(2)(99:1)
end
$ gfortran-6 z2.f90
f951: out of memory allocating 18446744073709551232 bytes after a total of
626688 bytes
Compiles and works :
$ cat z3.f90
program p
character(99), parameter :: x(2) = 'x'
character(99) :: y
y = x(2)(99:1)
print *, y
end
Works with a scalar x instead of an array :
$ cat z4.f90
program p
character(99), parameter :: x = ' '
character(99), parameter :: y = x(99:1)
print *, y
end
