Confirmed, checking merely gives us a more informative answer.  The compile
dies on the same line without checking too.  Without checking I get:

Program received signal SIGSEGV, Segmentation fault.

(gdb) p *container

  volatil = 0, in_struct = 0, used = 0, integrated = 0, frame_related = 0,
  u = {fld = {{rtint = 0, rtuint = 0, rtstr = 0x0, rtx = 0x0, rtvec = 0x0,
        rttype = VOIDmode, rt_addr_diff_vec_flags = {min_align = 0,
          base_after_vec = 0, min_after_vec = 0, max_after_vec = 0,
          min_after_base = 0, max_after_base = 0, offset_unsigned = 0,
          scale = 0}, rt_cselib = 0x0, rtbit = 0x0, rttree = 0x0, bb = 0x0,
        rtmem = 0x0, rtreg = 0x0}}, hwint = {0}}}


With checking, I get:
