Description Dale Ranta 2005-04-12 15:52:27 UTC 
I was trying to reduce a test case and I hit another error in the process -

[dranta:~/tests/gfortran] dir% gfortran -fdefault-integer-8 -o adini adini.f
adini.f: In function 'MAIN__':
adini.f:5: internal compiler error: in gfc_conv_string_tmp, at
fortran/trans-expr.c:736
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
[dranta:~/tests/gfortran] dir% cat adini.f
      program main
      character*6 hed
      character*6 final
      data final /'stop' /
      if (hed(1).eq.final) stop
      stop
      end

ftnchek saystroutmask:sgk[221] ftnchek a.f

FTNCHEK Version 3.2 November 2002

File a.f:
 0 syntax errors detected in file a.f
Warning: Subprogram HED never defined
    Invoked in module MAIN line 6 file a.f
    (possibly it is an array which was not declared)

With the above modification, the program compiles fine.

Your original program does cause an ICE with 
-fdefault-integer-8, but it fails to link with
a missing subroutine hed_ with it.

Aren't these fixed? Trying to compile these testcases with an up-to-date
compiler, I don't get ICEs...
Comment 7 Andrew Pinski 2005-09-12 15:21:55 UTC 
Fixed at least on the mainline.
