Newbie help: Segmentation fault

Hi again,

First of all thanks for your reply. It sound logical, but doesn't work
unfortunately. I now get:

seabert:/var/pear# phpunit Test_Standard_qconf
PHPUnit 3.0.0alpha11 by Sebastian Bergmann.

FFFFSegmentation fault

I've got no idea where the the FFFF stands for.

/**

• Parse .ini content into a zend array
  */
  PHP_FUNCTION(qconf_ini_parse)
  {
  zval *in=NULL;
  zval *ret=NULL;

  if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "z|z", &in,
  &ret) == FAILURE) {
  RETURN_FALSE;
  }

  if (ret != NULL) {
  printf('1');
  }
  RETURN_NULL();
  }

If you could have a closer look I will be very grateful.

Arnold

Hi,

I could use some help on an extension I've written. It worked fine
before, but from out the blue I started to get segmentation faults.
I've located it down to this piece of code, but I don't do any writes
to the code memory, so I don't get what's wrong. It seems like the
error lies in the 'ret != NULL'.

The module compiled against php 5.1.6 and runs under linux version
2.6.15.4 (Debian).

• zval *ret;
  

• zval *ret = NULL;
  

Hi,

Yes sure you are right, but there was some other code which I replaced
with printf to show where the problem lies. The printf not in the actual
code, only in the e-mail :).
I'm very sure that the problem lies in the ret != NULL. Function
zend_parse_parameters() puts a strange value in ret, when the argument
is not supplied in PHP. But I'll try gdb to see if I can find where the
problem is coming from.

Thanks for replying anyway,
Arnold

'1' is 0x00000031, use "1" and you'll get a real memory address to print.
