[Bug fortran/66065] New: ICE on assignment to deferred-length character array

            Bug ID: 66065
           Summary: ICE on assignment to deferred-length character array
           Product: gcc
           Version: 5.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: damian at sourceryinstitute dot org
  Target Milestone: ---

I see several other deferred-length character variable bug reports, including a
few ICE report, but I think this is sufficiently different from the others to
warrant a separate submission:

$ cat parse_command_line.f90 
character(len=:), allocatable :: original,copy(:)
copy = [original]
end 

$ gfortran parse_command_line.f90 
parse_command_line.f90:2:0:

 copy = [original]
 ^
internal compiler error: in gimplify_var_or_parm_decl, at gimplify.c:1797

parse_command_line.f90:2:0: internal compiler error: Abort trap: 6
gfortran: internal compiler error: Abort trap: 6 (program f951)
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://trac.macports.org/newticket> for instructions.

Hi Dominique,

Do you know if anyone is working on fixing this bug?  Would it be worthwhile
for me to mail the gfortran developers list for an update?

Nobody as far as know.
