OK, knowing *exactly* what is going on when there are lots of other
peoples code involved (a framework, ADODB, JPSpan, etc.) is tuff, but
here is what I think:

The lowdown: mysqli seems to be gone by the time the shutdown function
is called (the error being "Couldn't fetch mysqli"). That makes an
exception, and depending on whatever else is loaded, it will either
try to squelch the error or throw a new exception which leads to the
error at Unknown at line 0 bug.

At any rate, there are two problems:
1) That the newly thrown exception blows up into a fatal error that
doesn't list the file or line number.

2) mysqli is unloaded(!?) (or appears to be) before the the user's
shutdown function is called. This one is SERIOUS -- I use it to save
session data, etc. This then becomes impossible to do.

In the backtrace you'll notice that the function table (in fact, all
parameters, are, as Markus says, borked!) when going from
call_user_function() to call_user_function_ex() on the mysqli
extention.

I guess I should make a bug report or two. ??
