Operating system: Linux 2.4.12
PHP version: 4.2.3
PHP Bug Type: Zend Engine 2 problem
Bug description: zend_get_parameters_ex segfault PHP on script end
I have an extension which is working well in PHP 4.2.2 but when I compile
it with PHP 4.2.3. The scripting engin crash on the end of the script
several times. I comment out the zend_get_parameters_ex and put static
parameters and the script work well.
There is the function in my extension (every function using parameter may
crash PHP)
PHP_FUNCTION(ia_open)
{
zval **spHost_arg, **spPort_arg;
char *spHost = NULL;
char *spPort = NULL;
TIA_Stream* olStream;
TIA_Stream* olResStream;
TIA_Writer* olWriter;
TIA_Reader* olReader;
int sockfd;
int nlRes=-1;
//If I use this it may crash PHP
#if 0
if (ZEND_NUM_ARGS() != 2 || /*this part may crash
PHP*/zend_get_parameters_ex(2, &spHost_arg, &spPort_arg) == FAILURE){
WRONG_PARAM_COUNT;
}
convert_to_string_ex(spHost_arg);
spHost = Z_STRVAL_PP(spHost_arg);
convert_to_string_ex(spPort_arg);
spPort = Z_STRVAL_PP(spPort_arg);
#else //It's ok with this code
spHost = "xxxxx";
spPort = "1111";
#endif
sockfd = connecttounix();
olStream = new TIA_Stream();
olWriter = new TIA_Writer(olStream);
olWriter->WriteInteger (knIA_Open);
olWriter->WriteString (spHost);
olWriter->WriteString (spPort);
delete olWriter;
olResStream = new TIA_Stream();
if ( request(sockfd, olStream, olResStream) == 0)
{
olReader = new TIA_Reader(olResStream);
nlRes = olReader->ReadInteger();
delete olReader;
}
delete olResStream;
delete olStream;
disconnectfromunix(sockfd);
RETURN_LONG (nlRes);
}
There is some output of PHPINFO
