The faulting instruction is:
  74:   52 82 00 20     ldd 10(r20),rp

Which is just before the curr->func call.
  78:   e8 40 f0 00     bve,l (rp),rp
  7c:   52 9b 00 30     ldd 18(r20),dp

So your assumption was correct. The value of curr->func is null.
How did the list get corrupted?

Cheers,
Carlos.
