My apologies, I should have tried a cvs snapshot before submitting the
bug report.

Okay, here's the backtrace:

One additional note, once I compiled with --enable-debug, passing
MYSQLI_USE_RESULT to mysqli_query() caused it to print "Query was
empty" instead of segfaulting (no matter what the query was).
Just for the record, here's my reproduce script:
<?php
$link = mysqli_connect("db.telana.com", "root", "*******");
$result = mysqli_query($link, "SHOW DATABASES") or
die(mysqli_error($link));
while(list($database) = mysqli_fetch_array($result, MYSQLI_ASSOC))
echo "$database\n";
mysqli_free_result($result);
mysqli_close($link);
?>

Description:
------------
This is exactly the same as bug #28933, except it's still happening for
me on PHP 5.0.3 on x86_64. I would have added a comment to that bug but
it's been closed.
The only other info I've seen on the net related to this is something
about mixing 32-bit and 64-bit libraries. I'm running a pure 64-bit
system so that's not the problem.
I tested this with the simplest possible configuration: "./configure
--with-mysqli=/usr/bin/mysql_config" and ran the test script
(functionally identical with the one in #28933) with the CLI version,
using php.ini-dist.
Tested with mysql versions 4.1.7 and 4.1.10.
Reproduce code:
---------------
See bug #28933
Expected result:
----------------
PHP to not segfault :)
Actual result:
--------------
PHP segfaults :(
