Bug ID: 100776
Summary: Error in automatic object of parameterized derived
type
Product: gcc
Version: 11.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: furquan2011 at gmail dot com
Target Milestone: ---
gfortran gives a compilation error while trying to use an automatic object of a
parameterized derived type. For example, trying to compile
```
module vector
type :: vec(dimen)
integer,len :: dimen
real :: e(dimen)
end type vec
contains
function double(a)
type(vec(*)),intent(in) :: a
type(vec(a%dimen)) :: double
double%e = 2.*a%e
end function double
end module vector
results into the following error:
Error: The AUTOMATIC object ‘double’ at (1) must not have the SAVE attribute or
be a variable declared in the main program, a module or a submodule(F08/C513)
As much as I know, there is no SAVEd variable here. The code works without
issues with intel and NAG compilers.
