I've been following through with the debugger:
=20
$class->primary_column() works in my code just before I call create, but
it fails catastrophically in Class::DBI::_create.=20
=20
$class->columns() continues to work in both.

Subject: Death by deep recursion: why might this be?
Hi,=20
I'm not sure what's going on here.=20
I'm trying to create a Class::DBI subclass object from within my
code, and it's consistently crashing with a segmentation fault.=20
The problem goes away when I call create on the same class and
parameters, but with fewer modules. I'm not asking anyone to pinpoint
the problem - I'm guessing that it is in my code's use of Class::DBI
somewhere, because I can get the same method call to work out of this
context ... but I'd like to know what *might* be causing it.
This is a Trace of the last few moments of the executable:=20

This is some debugging output, verifying that the columns are
properly set up. The id column is a MySQL auto_increment column, which
is why it isn't set in my create call.
