Hi

Does it happen if you initialize zval *res to NULL? and does it happen
with the latest 5.3.x release, 5.2.x and trunk versions of those?

So having not tried any newer snapshots than php5.3-201004220030 I went
ahead and grabbed php5.3-201005111430.  Using '--with-mysql=mysqlnd' the
script executes as expected (no segfault), however, the segfault still
occurs with '--with-mysql'.  If you'd like I can bisect my way through
the snapshots until I find the point at which this became true, but if
that's not going to be useful I'd just as soon not.  Let me know if I
can provide additional information.

No change using --with-mysql=mysqlnd =/

As a side note, can you try building PHP with the following option
--with-mysql=mysqlnd and run the code again? I tried today your script
on FreeBSD6 64bit and had no crash, however it was mysqlnd. mysqlnd
shouldn't affect this but I want to be sure that this unknown is removed
from the equation.
Thanks!
