Do you mean the following:

(gdb) p debug_tree (t)
 >
sizes-gimplified unsigned SI
size 
unit size 
align 32 symtab 21 alias set -1
pointer_to_this >

arg 0 

arg 0 
addressable used unsigned SI file ../../gcc/gcc/libgcov.c line 775
size  unit size

arg 1  constant

What is the actual triplet, and can you provide a .i file?

  t = build2 (GIMPLE_MODIFY_STMT, valist_type, valist, t);

  ofs = (8 - size) % 4;
  if (ofs != 0)
{
  u = fold_convert (valist_type, size_int (ofs));
  t = build2 (PLUS_EXPR, valist_type, t, u);
}

  t = fold_convert (ptr, t);
  t = build_va_arg_indirect_ref (t);

So we are building (*(cast)(valist = t)) which we can no longer do as we are
using GIMPLE_MODIFY_STMT.
