php 8.1 segmentation fault

sya54M · 12-28-2021, 10:37 AM

Hi everyone, I installed the new php 8.1 from Slackware arm extra packages, but it seems buggy to me, it crashes on mysqli_query() when connected to local database.
Pat reintroduced the 8.0 on x86, but only 8.1 is left on arm.
Can anyone help me?

Those with no other options must be content with what is offered. Merry Christmas.

here is the crash:

Code:

php-cgi: malloc.c:2539: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.

Do you have some code to reproduce this? you're using the cgi so hopefully it's reasonably straight forward and doesn't require the set up of an httpd.

Does php 8.0 work when you compiled it? I hadn't got around to adding php 8.0 to /extra yet but I'll put it in the queue.

Code:

$mysqli = new mysqli("localhost", "my_user", "my_password", "my_db"); //very important that the host is set to localhost
$result = $mysqli->query("SELECT * FROM my_table");

Doesn't require the set up of an httpd.

With the 8.0 version work fine.

I have reported the problem also in the php site:
https://bugs.php.net/bug.php?id=81696

Confirmed! It works with the php 7 though, and I imagine it'll also work with 8.0 since it does for you.

Thanks. I have to say, this is one of the best bug reports I've ever had! I think you've solved it yourself :-)

I tested on AArch64 as well, and it fails with php 8.0 and 8.1

Code:

php 8.0:

I see in the report that you built it with debugging enabled. The PHP SlackBuild you were directed to previously isn't the official Slackware build script, so I don't know if it has different build options which happen to fix this. The official build script is here.
http://ftp.slackware.com/pub/slackwa...t/extra/php80/

PHP 8.0 is building on 32bit ARM now so I'll have a look at that in the next few days.

That's the php8 package. For the official php80.SlackBuild script he'll want this URL: http://ftp.slackware.com/pub/slackwa.../source/php80/ ?

The official script includes '--enable-maintainer-zts --with-xmlrpc=shared --with-expat' build options where the GitHub script doesn't.
