Hi,

I've been doing some work on making Xdebug run with PHP 8.1 (master)
again, and after my fixes
(https://github.com/xdebug/xdebug/pull/728/files) I am still running
into a crash (or rather, assert, in opcache):

php: /home/derick/dev/php/php-src.git/ext/opcache/zend_persist.c:327: zend_accel_get_type_map_ptr: Assertion `ret > 2' failed.

To reproduce:
- Check out xdebug from GIT, and switch to the php81-fixes branch:
git clone git@github.com:derickr/xdebug.git && cd xdebug && git checkout php81-fixes

- Compile and install
phpize && ./configure  --enable-xdebug-dev && make clean && make all && make install

- Run tests:
OPCACHE=yes php run-xdebug-tests.php
(This should show the error, and create the .php file used below):

- For an individual test that shows it (with php.ini disabled):
/usr/local/php/master-zts/bin/php -n -dzend_extension=opcache -dzend_extension=xdebug -d "opcache.enable=1" -d "opcache.enable_cli=1" -d "opcache.optimization_level=-1" -d "xdebug.mode=coverage" -d "xdebug.start_with_request=default" -f "/home/derick/dev/php/derickr-xdebug/tests/coverage/coverage4-php74.php"

- Loading order does not matter:
/usr/local/php/master-zts/bin/php -n -dzend_extension=xdebug -dzend_extension=opcache -d "opcache.enable=1" -d "opcache.enable_cli=1" -d "opcache.optimization_level=-1" -d "xdebug.mode=coverage" -d "xdebug.start_with_request=default" -f "/home/derick/dev/php/derickr-xdebug/tests/coverage/coverage4-php74.php"

- Not loading opcache does work:
/usr/local/php/master-zts/bin/php -n -dzend_extension=xdebug -d "opcache.enable=1" -d "opcache.enable_cli=1" -d "opcache.optimization_level=-1" -d "xdebug.mode=coverage" -d "xdebug.start_with_request=default" -f "/home/derick/dev/php/derickr-xdebug/tests/coverage/coverage4-php74.php"

We already made few significant changes in PHP-8.1.
e.g. most classes and methods are immutable.
It's not allowed to change them (this is the same as before, but now almost
all of them are immutable). Use opcache.protect_memory=1 to catch
potentially wrong modification.

From the quick look, I don't see how zend_map_ptr_new() may return 0 or 1
at this point.
I'll be able to run xdebug tests only in the middle of the next week.

Thanks. Dmitry.

Hi,

turns out that this test fails even without Xdebug even loaded, so it's
not something on my side :-)

Just run it as:

wget https://derickrethans.nl/files/dump/xdebug_var_dump_typed_properties-text.php.txt -O xdebug_var_dump_typed_properties-text.php
php -n -dzend_extension=opcache -d "opcache.enable=1" -d "opcache.enable_cli=1" -d "opcache.optimization_level=-1" -f xdebug_var_dump_typed_properties-text.php

Result:

php: /home/derick/dev/php/php-src.git/ext/opcache/zend_persist.c:327:
zend_accel_get_type_map_ptr: Assertion `ret > 2' failed.
Aborted

I suppose, something is wrong with your build.
This code works fine for me.
Please, try full rebuild.

Thanks. Dmitry.

Hi,

It's not just my own build, see this one on OSX on Azure Pipelines (line
427):

https://dev.azure.com/php-xdebug/Xdebug/_build/results?buildId=388&view=logs&j=fa4207ea-b23d-55f8-a438-8fcfe0ff1a84&t=a376e1dc-bcfe-530b-98ce-61c964f8af0f&l=425

Which is a build from scratch.

And I've locally also just rebuild from scratch, but still getting the
same result.

My build log:
http://derickrethans.nl/files/dump/master.log

My configure line:
'./configure'  '--prefix=/usr/local/php/master' '--enable-debug' '--with-gettext' '--with-gd' '--enable-gd' '--with-jpeg' '--without-freetype' '--with-jpeg-dir=/usr' '--without-freetype-dir' '--with-mysql=mysqlnd' '--enable-bcmath' '--with-readline' '--with-openssl' '--without-esmtp' '--with-curl' '--with-sodium' '--with-ffi' '--with-mysqli' '--enable-pcntl' '--enable-sockets' '--enable-zip' '--with-zip' '--enable-memory-limit' '--with-mcrypt' '--with-libxml' '--enable-libxml' '--with-iconv' '--enable-wddx' '--enable-calendar' '--with-sqlite3' '--enable-spl' '--enable-pdo' '--with-pdo-mysql' '--with-pdo-sqlite' '--with-ctype' '--with-bz2' '--enable-mbstring' '--with-mime-magic' '--with-xmlrpc' '--with-zlib' '--disable-zend-memory-manager' '--with-esmtp' '--with-xsl' '--enable-exif' '--enable-soap' '--enable-ftp' '--enable-intl' '--enable-opcache' '--enable-fpm' '--enable-fileinfo' '--with-pear'

I can't reproduce this on Linux.

[dmitry@tpl2 xdebug]$ php run-xdebug-tests.php -d opcache.enable=1 -d
opcache.enable_cli=1 -d opcache.optimization_level=-1
tests/tracing/functrace_typed_properties.phpt

...
PHP_VERSION : 8.1.0-dev
...
PASS Test for function traces with typed properties
[tests/tracing/functrace_typed_properties.phpt]
...

Thanks. Dmitry

That's curious. I'm locally on Debian Linux, and Azure pipelines is on OSX. How can we figure this out? Want to do a screenshare or something? Perhaps it's a compiler issue? I'm building in debug mode FWIW. And see it with and without ZTS.

Did you try my one liner without xdebug involved at all too?

cheers,
Derick

Do you use CLANG on Linux?
I won't be able to work on this before March 9.

Everything works fine for me.
We test OSX build without xdebug on Azure, and didn't see a similar problem.

Thanks. Dmitry.

No, GCC 10:
gcc version 10.2.1 20210110 (Debian 10.2.1-6)

I think it could perhaps use GCC on Azure/OSX too:

https://dev.azure.com/php-xdebug/Xdebug/_build/results?buildId=388&view=logs&j=fa4207ea-b23d-55f8-a438-8fcfe0ff1a84&t=9acc530a-b2bd-54c1-05de-84dd64697faa&l=86

85: checking whether we are using the GNU C compiler... yes

But I'm not sure whether CLang would respond the same.

Hello,

I was also able to reproduce the error.

I used the latest available "daily" cloud image for Debian Buster and
created a small recipe to reproduce. Hopefully this helps in finding the
problem.
