Bug ID: 77603
Summary: ICE: Segmentation fault (program f951)
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: [email protected]
Target Milestone: ---
Invalid code with a cyclic length declaration.
Related to pr77602, basically an analogous problem with a somewhat
different behaviour. Generates an ever growing file "m.mod0".
Similar to argument_checking_7.f90 from testsuite, i.e. pr31306.
$ cat z1.f90
module m
contains
function zfn(x,y)
implicit character(len(zfn)) (x)
implicit character(len(x)+1) (y)
implicit character(len(y)-1) (z)
intent(in) :: x, y
character(len(y)-1) :: zfn
integer :: i = 1
zfn = achar(max(iachar(x(i:i)),iachar(y(i:i))))
end
end
$ time gfortran-7-20160911 -c z1.f90
gfortran: internal compiler error: Segmentation fault (program f951)
