[Bug fortran/16487] New: gfortran core dump on big array

["olchansk at panix dot com" <gcc-bugzilla at gcc dot gnu dot org>]

gfortran version "gcc version 3.5.0 20040710 (experimental)" dumps core on this
test program:
[olchansk@tw15 gfortran_test]$ more test_bigarray.f90
module foo
  !
  ! gfortran: Internal error: Segmentation fault (program f951)
  ! Please submit a full bug report.
  ! See <URL:http://gcc.gnu.org/bugs.html> for instructions.
  !
  ! Error goes away if "=0" initializer is removed.
  !
  integer:: a(44,80,79) = 0
end module foo
[olchansk@tw15 gfortran_test]$ make test_bigarray.o
/triumfcs/trshare/olchansk/gcc-tree-ssa/install/bin/gfortran -x f95 -c  -o
test_bigarray.o -O2 -g -Wall -Waliasing -Wline-truncation -Wsurprising
-Wunused-labels -fPIC -ffixed-line-length-132 test_bigarray.f90

make: *** [test_bigarray.o] Error 1
[olchansk@tw15 gfortran_test]$ ls -l core.21563 
-rw-------    1 olchansk users    16584704 Jul 11 19:14 core.21563

The core dump is garbled- it appears to show an infinite recursion at
"gt_ggc_mx_lang_tree_node (x_p=0x4046e960) at gt-fortran-f95-lang.h:155".

K.O.
