I'm not a C++ hacker, but I think I grok the problem. Presumably you have a Perl object which is wrapping a C++ object, and the Perl object's class has a DESTROY function which deletes the C++ object. You can override that DESTROY function and stop it from cleaning up the C++ object, but you'll end up with a memory leak. Another possibility is to save a local copy of the Perl object, using the perlapi function newSVsv, so that when the last Perl-space reference drifts out of scope, you still have a reference keeping it from being destroyed.

Caveat: this is a hard problem, and if you're not familiar with how and when DESTROY gets invoked and does its work, the above advice probably just gives you rope to hang yourself with.
