Description:
------------
There is an error on the PCRE extension and memory management, I can't determine exactly
what's happening, I have These 2 types of messages :
php7(42118,0x7fff7e1dd300) malloc: *** error for object 0x7f8022f02b28: incorrect checksum for freed
object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6
Assertion failed: (function->type == 1), function zend_function_dtor, file
/Users/gplanchat/CLionProjects/php-src/Zend/zend_opcode.c, line 122.
Abort trap: 6
This is the configure command I used on my mac :
./configure --prefix=$HOME/tmp/usr --with-config-file-path=$HOME/tmp/usr/etc --enable-mbstring
--enable-zip --enable-bcmath --enable-pcntl --enable-ftp --enable-exif --enable-calendar
--enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-wddx --with-curl --with-mcrypt
--with-iconv --with-gmp --with-gd --with-jpeg-dir=/usr/local/opt/jpeg/include/
--with-png-dir=/usr/local/opt/libpng/include/ --with-zlib-dir=/usr --with-freetype-dir=/usr
--with-t1lib=/usr --enable-gd-native-ttf --enable-gd-jis-conv --with-openssl
--with-pdo-mysql=mysqlnd --with-gettext=/usr/local/opt/gettext/ --with-zlib=/usr --with-bz2=/usr
--with-recode=/usr --with-mysqli=mysqlnd --enable-debug --enable-maintainer-mode
I'm using OSX 10.10 Yosemite, with the latest master
(34ff6bbb0df152694e648161b149d41270fccdcb).
Test script:
---------------
<?php
$buffer = 'public function test(){return true;}';
preg_match('/(?:public|protected|private|final|abstract|static)*?'
. '\s+function\s+test\([^\)]*\)\s*(?:\{(?:[^{}]*|(?R))*\})/sm',
$buffer, $matches);
var_dump($matches[0]);
Expected result:
----------------
string(36) "public function test(){return true;}"
Actual result:
--------------
Either :
php7(42118,0x7fff7e1dd300) malloc: *** error for object 0x7f8022f02b28: incorrect checksum for freed
object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6
Or either :
Assertion failed: (function->type == 1), function zend_function_dtor, file
/Users/gplanchat/CLionProjects/php-src/Zend/zend_opcode.c, line 122.
Abort trap: 6
