Segmentation fault after "Generating autoload files" with php-5.6.0alpha3

[sylvainfilteau]

I just compiled php-5.6.0alpha3 and tried installing dependencies of composer using... composer ! Unfortunately, I get a "Segmentation fault" error after the "Generating autoload files" message.

Here are the step used to compile php-5.6.0alpha3 on Ubuntu 13.10:

# Install base dependencies
sudo apt-get install apache2 apache2-dev build-essential libxml2-dev \
    libcurl4-openssl-dev libgmp-dev

# Necessary to make work the GMP extension
ln -s /usr/include/x86_64-linux-gnu/gmp.h /usr/include/gmp.h

# Download and install PHP 5.6.0alpha1
wget http://downloads.php.net/tyrael/php-5.6.0alpha3.tar.bz2
tar -xjvf php-5.6.0alpha3.tar.bz2
cd php-5.6.0alpha3
./configure --with-curl --with-gmp --enable-mysqlnd --enable-opcache \
    --with-openssl --with-pdo-pgsql --enable-phpdbg --with-pgsql --enable-zip \
    --with-apxs2
make

# Not all tests passed here
make test

make install

The I git cloned composer and runned composer:

Generating autoload files
Segmentation fault (core dumped)

I tried debugging it but I cannot run unit tests on the repository because I cannot install it's dependencies (fuck me). I think it may be related to the extensions I installed or something like that...

Maybe someone can help me generate the autoloader manually so I can properly unit test ?

Thanks !

Don't you have access to another php version you could run the initial install with?

[Seldaek]

The test suite runs on alpha1 at least - if you can't figure it out I'll try to get me an alpha3 later.

[sylvainfilteau]

I wasn't able to run it on alpha1 too... so it must be something with my
setup then.

I was able to pinpoint the exact line causing the Segmentation Fault. It is \Composer\Autoload\ClassMapGenerator::findClasses at line 101, the function php_strip_whitespace.

The following gist is the minimum to reproduce the problem: https://gist.github.com/sylvainfilteau/9359062

It's a PHP issue, you can see a bug report about that there: https://bugs.php.net/bug.php?id=66751

[Seldaek]

Yes it's definitely a php issue and please report it to bugs.php.net if
you haven't done so :) That's the kind of stuff we really want them to
fix before the stable release.

hi,
should be fixed in the PHP-5.6 branch, you could test it with the latest snapshot or in the upcoming beta2:

Thank you for this fix. I can confirm Composer now works OK with the latest 5.6 snapshot. Regards.

Same problem (at least same symptom) with php-5.6.0beta1 (from Sury PPA) on Ubuntu 14.04. "Generating autoload files. Segmentation fault (core dumped)".

[Seldaek]

@fgm Tyrael said above it'll be fixed in beta2 so I guess it's been applied after beta1 was tagged :)

Indeed this no longer happens with a custom PHP build of todays 5.6 HEAD (with unsupported Bison 3.0.2 !), thanks.
