Description:
------------
When turned on opcache, the first call to extension function normally , the second appeared Segmentation fault. Close opcache is normal.Through debug and found add_assoc_stringl,add_assoc_long caused Segmentation fault when turned on opcache
Test script:
---------------
ZEND_FUNCTION( L5ApiGetRoute ){
double d_time_out = 0;
std::string err_msg;
zval *za_qos_req;
if ( ZEND_NUM_ARGS() == 2 ){
if ( zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "ad",&za_qos_req,&d_time_out) == FAILURE ){
RETURN_LONG(-2);
}else{
WRONG_PARAM_COUNT;
RETURN_LONG(-3);
}
php_var_dump(za_qos_req, 1);
add_assoc_stringl( za_qos_req, "hostIp", "10.175.90.28", 12);
add_assoc_long( za_qos_req, "hostPort", 80 );
}
PHP code:
<?php
$l5_req = array(
'modId' => 64100225,
'cmdId' => 65536
);
$l5_time_out = 0.2;
$ret = L5ApiGetRoute($l5_req, $l5_time_out);
print_r($l5_req);
$l5_reqx = array(
'modId' => 64000833,
'key' => 3
);
$ret = L5ApiGetRoute($l5_reqx, $l5_time_out);
print_r($l5_reqx);
?>
PHP.INI(opcache config)
zend_extension=opcache.so
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=10
opcache.fast_shutdown=1
opcache.enable_cli=1
Actual result:
--------------
