Greetings,
just an heads up, I started testing my project with PHP 7.2.0RC2 but it was
causing a segmentation fault.
I tracked down the problem to preg_match(), in particular when JIT is
enabled and ONLY when running through Apache2 with event MPM. This problem
does not occur with command line invocation.
Here are the versions I tested, same environment:
7.1.9 works with PCRE JIT enabled
7.2.0alpha1 broken
7.2.0rc2 broken
Build command line:
./configure \
--with-apxs2=/usr/local/apache2/bin/apxs \
--with-fpm-user=httpd \
--with-fpm-group=httpd \
--disable-cgi \
--enable-intl \
--with-layout=GNU \
--enable-maintainer-zts \
--with-gettext=static \
--with-iconv \
--with-mysqli=mysqlnd \
--enable-exif \
--with-openssl \
--with-curl
The effect i observed is the following:
var_dump(preg_match('/^a/', "a")); => int(0)
var_dump(preg_match('/a/', "a")); => segmentation fault
If you need any further information let me know.
Kind regards
