Dear Andrew,

When you want help, listen to those providing it.

I said "dbi-users@perl.org" - not dbi-dev.

However, given the volume of output, maybe it is just as well.  Fewer people got the overload of email.  We needed to know what the error was -- we can't guess at what your trouble was.  But we really didn't need each of the test lines.

When you get to the relevant places, you find that the problem is in the t*_85gofer.t tests - and looks like:

There's a memory management problem - clearly.

Equally, I am far from convinced anyone is going to be interested in debugging this problem for an archaic version of Perl (especially since the problem almost certainly does not reproduce in the current version.

My strong recommendation would be to upgrade to Perl 5.10.0; failing that, upgrade to 5.8.8.

You may get lucky and someone may be prepared to help with your actual configuration, but I have serious doubts.
