 The regression reported in PR optimization/7675 showed up
 starting with this patch:
 
 2000-11-11  Jason Merrill  <jason@redhat.com>
 
         * function.c (assign_parms): If TREE_ADDRESSABLE is set, try to
         give the parm a register and then call put_var_into_stack.
         * stmt.c (expand_decl): Likewise.
 
 cp/
         * typeck.c (mark_addressable): Don't call put_var_into_stack.
 
 Here's a small test case that causes the compiler to ICE
 when compiled on i686-linux with -O:
 
 -------------------
 /* ICE when compiled with -O */
 
 int dummy (int *);
 
 void foo(int i, int j)
 {
   int k=j;
 
   void bar() { int x=k, y=i, z=j; }
 
   dummy(&j);
 }
 -------------------
 
 Output from the mainline compiler:
 
 7675.c: In function `foo':
 7675.c:9: internal compiler error: in fixup_var_refs_1, at
 function.c:1900
