if the object is new'd in MAIN; and passed to routines (via @_); no problems
if the object is new'd in a routine; and passed to MAIN (either by return,or global var) problems (dumps core)
the odd thing is that if the object is new'd in a routine and passed to another routine (via @_) no problems.

I can't quite follow that. If "the object is new'd in a routine and passed to another routine (via @_)" doesn't it first need to be passed to "MAIN" - which, you say, dumps core ? That is, how do you pass the object that was "new'd in a routine" to "another routine (via @_)" without first passing that object to "MAIN" ?

Sorry if I'm being dumb :-)

Anyway, seems to me that the issue is probably one that can only properly be fixed in the C++/XS code (rather than your perl code) ... but it's hard to tell from the info you've provided.

Cheers,
Rob
