[Bug fortran/23323] New: Internal compiler error with CHARACTER functions and -fdefault-integer-8

[georg dot denk at infineon dot com]

When compiling the following subroutine test.F:

--- snip ----
      SUBROUTINE BUG(ID,PARNAM)

      IMPLICIT NONE

C     .. Scalar Arguments ..
      CHARACTER *8 PARNAM
      INTEGER      ID

C     .. External Functions ..
      CHARACTER *8 PANAME
      EXTERNAL     PANAME
C
      PARNAM = PANAME(ID)
C
      RETURN
      END
--- snap ----

using 

gfortran -v -save-temps -fdefault-integer-8 -c test.F

gives an internal compiler error:

Removing the option -fdefault-integer-8 gives a sucessful compile.
