[Bug fortran/106242] New: Internal compiler error: Parameterised derived types

Bug ID: 106242
   Summary: Internal compiler error: Parameterised derived types
   Product: gcc
   Version: 12.1.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: fortran
  Assignee: unassigned at gcc dot gnu.org
  Reporter: kidon at posteo dot de
  Target Milestone: ---

The following example code implements nested parameterised derived types:

module test
type :: foo_type(n)
integer, len :: n
character(len=n) :: s
end type foo_type

type :: bar_type(n)
integer, len:: n
type(foo_type(n=n)) :: foo
end type bar_type
contains
subroutine set_bar(bar, s)
type(bar_type(n=*)), intent(inout) :: bar
character(len=*),intent(in):: s

bar%foo%s = s
end subroutine set_bar
end module test

program main
use :: test
type(bar_type(n=10)) :: bar

call set_bar(bar, 'foo')
end program main

Trying to build the example with GNU Fortran 12.1 on FreeBSD 13.1 results in an
internal compiler error:

$ gfortran -freport-bug -o test test.f90
f951: internal compiler error: Segmentation fault

Yes, you are right. It is not a GNU Fortran bug; issue is resolved. Thank you
very much.

I use the official FreeBSD port for building GCC 6:

http://www.freshports.org/lang/gcc6

The dependencies are resolved automatically. I did not recompile them with
altered flags (all libraries are build without additional CFLAGS).

The following options have been used for building GCC 6:

BOOTSTRAP=on (Build using a full bootstrap)
GRAPHITE=off (Support for Graphite loop optimizations)
JAVA=off (Java platform support)

The libraries are linked dynamically.

Adding BOOT_CXXFLAGS doesn't help. The same error occurs.

Bug ID: 81253
   Summary: Flags -march and -mtune are ignored
   Product: gcc
   Version: 6.3.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: fortran

  Target Milestone: ---

I have built GCC 6.3.0 on a Intel Broadwell machine with FreeBSD 11. The binary
package of GCC is used on different client machines (each != Broadwell). Trying
to compile arbitrary Fortran code with GNU Fortran results in an internal
compiler error:

$ gfortran6 test.f08 -o test
: internal compiler error: Illegal instruction

It seems that Broadwell-specific instructions are compiled into GNU Fortran
even if additional flags to prevend this are set:

CFLAGS="-march=x86-64 -mtune=generic"
MAKE_ENV+= BOOT_CFLAGS="-march=x86-64 -mtune=generic"
CONFIGURE_ENV+= BOOT_CFLAGS="-march=x86-64 -mtune=generic"

These flags are ignored after stage 3 of the build process. The same behaviour
can be seen when building GCC 4.9/5.4/7.0.
