Now I install Gentoo from scratch, running on HP Proliant dual Xeon 3.6
(EM64T) 2GB RAM, with Linux Gentoo 2.6.22-r8 (64 bits)... so the example
works, but if I increase to 1,000,000 iterations it flaws again with: 

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 16 bytes) in /home/admin/gmp-test.php on line 6

No other services, nor heavy processes running...

Well, I tested against PHP 5.2.5 and it fails:

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to
allocate 12 bytes) in ./gmp-test.php on line 10

when trying to execute the example code.

I can not reproduce this using latest PHP 5.2.4-dev. 
So please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz

Description:
------------
Any gmp_* function running on PHP 5.2.2-r1 (compiled with GMP
extensions), throws after a few invokes "Fatal error: Allowed memory
size of <varies from 7M to 8M> bytes exhausted (tried to allocate 16
bytes) in <file.php>". 

Reproduce code:
---------------
for( $i= 0; $i!= 100000; $i++ )
{
  $node = gmp_init( $i );
  $id = gmp_div( $node, '0x100000000' );

  $edge = gmp_and( $node, '0xffffffff' );
  $vert = gmp_div( $node, '0x1000' );
  $path = gmp_and( $node, '0x00ff' );

  $str_edge = gmp_strval( $edge );
  $str_vert = gmp_strval( $vert );
  $str_path = gmp_strval( $path );

  echo "Graph -> ($str_edge, $str_vert, $str_path) \n";
}



Expected result:
----------------
The iterated procedure runs on PHP 5.1.x (and PHP 5.0.x) near to 1
million times per call.

In this case, it's only runs 500 times and then drop the Fatal error.


Actual result:
--------------
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to
allocate 16 bytes) in quixtor/compute-graph-map.php on line 443
(actually line 443 isn't a gmp related function, but it is called under
for() iteration which uses GMP functions).
