You are awesome.
That problem has been haunting me for half a year, and I've just been
ignoring it. Your description was enough for me to find the bug within 5
minutes. I had an Inline::CPP function returning an SV*, but I was
casting an HV* to SV* rather than making a reference.
Yay, I have the debugger back! (And I think it fixed another bug that
I've been meaning to hunt down...)
