Sharp eyes, but no joy. The mysql docs say mysql_real_connect() is safe to call
with db==NULL. But just in case, I checked it...

On the plus side, you led me to find a bug that was preventing dbname from
being passed in the param string. :)

Not that I know of. It's a default install with all the other dbd-related
modules commented out.
For kicks I tried running mysql under gdb with a breakpoint on my_stat() and
saw the following output. It seems that my_stat() has moved to a different line
in my_lib.c. That seems odd to me.

A few more breakpoints later and we get something more familiar...

But for some reason it doesn't segfault this time.
