Standard dance: 'make realclean'?

Yup.

That's directly from an isa opcode. Is $2 NULL or is $2->vtable NULL or is $2->vtable->isa_pmc NULL?

Demacrofying, that's:

  (gdb) print (&(interp)->ctx)->bp_ps.regs_p[-1L-(2)]
  $1 = (PMC *) 0xa52ab0

So $2 isn't null. and:

  (gdb) print (&(interp)->ctx)->bp_ps.regs_p[-1L-(2)]->vtable
  $2 = (VTABLE *) 0x9a04b0

So $2->vtable isn't null. and:

  (gdb) print (&(interp)->ctx)->bp_ps.regs_p[-1L-(2)]->vtable->isa_pmc
  $3 = (isa_pmc_method_t) 0x59

So, $2->vtable->isa_pmc isn't null.
