The resource limits section of php.ini is being ignored.

The ini file reads:

memory_limit = 6M

In a script it is possible to allocate well past this. I
succeeded in allocating over 100MB.

Sample:

$str = '';
$total = 0;

for ( $i = 0 ; $i < 65000 ; $i++ )
  $str .= 'a';

for ( $i = 0 ; $i < 1024 ; $i++ ) {
  printf(' %d (%d)', $i, $total);
  $strbuff[$i] = "$i - $str";
  flush();
  $total += strlen($strbuff[$i]);
}

# This allocates ~ 64MB

how does your configure line look like?

have you used '--enable-memory-limit' ?

it is _not_ enabled by default!

--with-memory-limit was not enabled 

maybe this is not clear enough in the manual or 
the comments in php.ini-dist ?

moved to documentation problems

I find this strange that this is not enabled by default.. Is there a
good reason for this?? Personally I think its somthing people assume is
turned on and should be on by default. Maybe there are good reasons for
it not being on by default. I will add a note in php.ini and the config
options in the manual later this evening 

This is actually fairly clear in the manual.. It is also clear when
doing ./configure --help. I added a note about default value to manual
but thats about all we can do.. we cant force people to read the docus
