Thanks for the explanation. I wasn't aware the use of
inferior_ptid happens in some of callback routines used
by the pthdb_session_init() library routine.
I still think the proposed fix isn't really ideal. Can you instead
try to *temporarily* (i.e. using a scoped_restore) set up inferior_ptid
in pd_activate() before calling pthdb_session_init(), with a comment
explaining that this is needed for the callbacks?
[ pd_activate currently gets a pid. If this isn't sufficient to set
up inferior_ptid, you might have to change the pd_activate interface
again to take a full ptid. ]
Bye,
Ulrich
