Definitely an FE oddity.  The operand scanner is told to get the operands of a
COMPONENT_REF that's accessing a non-existant field:

(gdb) ptu stmt
substr.ktbuf = D.485;
(gdb) ptu expr
substr.ktbuf;
(gdb) call debug_variable(ref)
substr, UID 475, struct
{
  int4 nphase;
  int4 nsub;
}, is global, call clobbered, sub-vars: { SFT.25 }
(gdb)

There is no field named 'ktbuf'.  This is confusing all the sub-var machinery,
leading to this ICE.

Paul, could you take a look?
