[Bug fortran/45092] New: internal compiler error regression bug in the latest trunk build of the gfortran compiler

[clerman at fuse dot net]

Hello,

  I am e-mailing to gcc-bugzilla@gcc.gnu.org file bug8.tar.gz. Please unpack it
and then invoke the shell script bug8.sh (the name of the compiler I'm
symbolically linked to is gfortran-trunk). The following message appears
compiling file functiontypeM.f90 (see file functiontypesM.xyz): 

norm@oxford:~/design/gfortran/bug8$ more functiontypesM.xyz
functiontypesM.f90:206.65:

    & [(0.0_DOUB_PREC, iPars = 1_TinyInteger, NUMBER_OF_TERM_PARS)], [" ", "
"])
                                                                 1
Warning: Possible change of value in conversion from INTEGER(4) to INTEGER(1)
at (1)
functiontypesM.f90:383:0: internal compiler error: in
output_constructor_regular_field, at varasm.c:5027
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

  This bug is a regression; versions 4.4 and 4.5 successfully compile the
routine.

  Please note that I question the warning message issued for line 206: All the
entities involved are of the same kind, so, I assume, no conversion should be
done.

  Thank you for your attention.

Yours truly,

Norman S. Clerman
consultant

Reset severity to normal.  Fortran bugs are rarely anything but
normal.

Here's an even shorter testcase.

MODULE FunctionTypes

  IMPLICIT NONE

  integer, parameter :: OpconNameLength = 4

  TYPE, PUBLIC :: TTermDefinition
    CHARACTER (OpconNameLength) :: termName(2)    
  END TYPE TTermDefinition

  TYPE (TTermDefinition), PARAMETER :: e = TTermDefinition ([" ", " "])

end module FunctionTypes

Yes, I think you're right.  I've reduced it further in 
comment #6.  The code compiles if the array constructor is
changed.  That is, this compiles

MODULE FunctionTypes

  IMPLICIT NONE

  integer, parameter :: OpconNameLength = 4

  TYPE, PUBLIC :: TTermDefinition
    CHARACTER (OpconNameLength) :: termName(2)    
  END TYPE TTermDefinition

  TYPE (TTermDefinition), PARAMETER :: e = TTermDefinition (["    ", "    "])

end module FunctionTypes

Mark as duplicate of PR 44857 as it is seemingly the same. As bonus, I might
have a patch.
