[Bug fortran/32926] New: Internal compiler error in the middle of a sizeable package build

[rbk at louisiana dot edu]

This bug occurred during a build of a version of "GlobSol" that builds
correctly with the g95 compiler.  It happens with the "unofficial" build
of gfortran for native Windows that I downloaded from
http://gcc.gnu.org/wiki/GFortranBinaries#Windows from the link: 
mingw build, or "native Windows": download the latest installer (dated
2007-07-06). 

The compiler output is:

gfortran bug report:

gfortran -c -Ic:\GlobSol_gfort c:\GlobSol_gfort\iterate\dogleg_opt.f90
c:\GlobSol_gfort\iterate\dogleg_opt.f90: In function 'search_dogleg':
c:\GlobSol_gfort\iterate\dogleg_opt.f90:144: internal compiler error: in
gfc_get_symbol_decl, at fortran/trans-decl.c:876
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
make: *** [c:\GlobSol_gfort\dogleg_opt.o] Error 1


I am not sure what else you need.  I could send the entire package source,
along
with the makefile, but the bug reporting instructions seemed to say
that it is not desired.  However, the source file that won't compile
uses two modules that are part of a hierarchy that must be compiled first.
I'm at a bit of a loss at present to isolate the problem further.  Please
communicate with me as appropriate.

Possibly a duplicate of PR 31213.

Hi Ralph,

Thanks for the bug report. Can you please email the sources to me privately
(fxcoudert@gmail.com). I will work out whether this is a duplicate of PR31213,
or a different bug (and will make a short testcase out of it).

Thanks,
François-Xavier

I will mention that pr31213 has multiple problems.  We have a partial fix that
appears to take care of one of these.  So if you get a reduced case here, we
can try it.

------- Comment #4 from fxcoudert at gcc dot gnu dot org  2007-08-06 09:49 -------
OK, I downloaded GlobSol and have a reduced testcase:

$ cat pr32926.f90
subroutine foo (fcn)
  external fcn
contains
  subroutine bar
    call fcn
  end subroutine bar
end subroutine foo
$ gfortran pr32926.f90
pr32926.f90: In function ‘bar’:
pr32926.f90:4: internal compiler error: in gfc_get_symbol_decl, at
fortran/trans-decl.c:890

The backtrace is:
