Here, the problem is that in
  #0  gfc_conv_string_init (length=0x2aaaacf3b720, expr=0x16c1170)
expr->type == EXPR_ARRAY. Hence, the following fails:
  gcc_assert (expr->expr_type == EXPR_CONSTANT);

#1  in gfc_conv_initializer at fortran/trans-expr.c:4940
#2  in gfc_conv_structure   at fortran/trans-expr.c:5396
#3  in gfc_conv_initializer at fortran/trans-expr.c:4933
#4  in gfc_get_symbol_decl  at fortran/trans-decl.c:1476

Also that version works with GCC 4.5.

Also 2010-08-28-r163612 fails.

I wonder whether the patch for PR 44857 (2010-08-04, Rev. 162863) is the
culprit:
