Figured it out and got:

(gdb) print *edata->prev_execute_data
$7 = {opline = 0x3, call = 0x4, return_value = 0x0, func = 0xfbcd80, This = {
    value = {lval = 0, dval = 0, counted = 0x0, str = 0x0, arr = 0x0, 
      obj = 0x0, res = 0x0, ref = 0x0, ast = 0x0, zv = 0x0, ptr = 0x0, 
      ce = 0x0, func = 0x0, ww = {w1 = 0, w2 = 0}}, u1 = {v = {type = 8 '\b', 
        type_flags = 12 '\f', const_flags = 0 '\000', reserved = 2 '\002'}, 
      type_info = 33557512}, u2 = {var_flags = 1, next = 1, cache_slot = 1, 
      lineno = 1, num_args = 1, fe_pos = 1, fe_iter_idx = 1}}, 
  called_scope = 0x7ffff3203018, prev_execute_data = 0x7ffff3213f20, 
  symbol_table = 0x7ffff327d090, run_time_cache = 0x40000c08, 
  literals = 0x1069c20}
