Got part of this done...

gdb program 27552 worked...


Attaching to Pid 27552

(gdb) print tds->in_pos
No symbol table is loaded.  Use the "file" command.
(gdb) file
A program is being debugged already.  Kill it? (y or n) n
Program not killed.
(gdb)

That's all I've got so far - I can't seem to print tds->in_pos,
unless it's not "print tds->in_pos"  - is there another way to do that?
