In the debugger Devel::Trepan, there is the ability to show B:OP addresses. There is an optional plugin which allows one to disassemble Perl subroutines and packages. But what I'd like to do is to be able to disassemble a more limited region around the OP address. So how can I do that?
I know about Devel::Pointer, but I can't get that to work here:
(trepanpl): disasm Devel::Trepan::Options::whence_file
...
OP (0x9961848)
op_next 0x9961828
op_sibling 0
op_ppaddr PL_ppaddr[OP_PADSV]
op_type 9
op_flags 0000000
op_private 0
(trepanpl): sprintf "%d", 0x9961848
$DB::D[7] = 160831560
(trepanpl): $c = deref(160831560)
** Bizarre copy of UNKNOWN in scalar assignment
$DB::D[8] = <undef>
Program received signal SEGV.

Thoughts or suggestions?
Thanks.
