You can also 'printf("%d\n", SvREFCNT(sv));' to view the reference

the count is).
There's been some weirdness in how the reference counts behave when
I've created SV*'s from within C. I couldn't really figure it out.
I worked around it in the particular section by passing an extra
argument from perl to use for output, so that the C function went
from returning an SV to void.
There is no generic C debugger, and hence no generic methods of C
debugging - except for using printf() statements.
As an addendum to my previous post: the Perl debugger just froze up
on encountering the segfault, so it wasn't any help. No surprise,
really.
Heh ... I've only just now seen Eric's post. Like him, the main
reason I
didn't post was that I didn't feel qualified. I actually did write
a reply
to your initial post, but then thought "naaaaaaaaaa ...". Sorry if my
timidity meant extra work for you :-)
I'll considering suing you for every penny our non-existent support
contract entitles me to.
Thanks for the help,
