Also trying with:
unset( variable );
variable = Null;
didn't free memory neither call the garbage collector, and in every
function pass I've got an increment near to 1 MB of alloc'd RAM.

You can achieve similar thing with any other variable,
it's not GMP related at all.
Due to the short answer I recieved, I can't understand what're you
telling me... I use GMP functions 'cos I need to make more calculations
that I've exposed on the example, which I can't achieve in 32 bits
operations.
I see that when I issue mysql_query( 'Select * from Table1 limit 0,
1000') I need to call mysql_free_result() to free memory used to store
the result in memory.
Consequently, with GMP functions which uses ZEND_REGISTER_RESOURCE
macro in gmp.c (wrapper for GMP functions), I suppouse that the
resource continue alloc'd, till a free() call releases it, according
with system memory test (experienced with a simple «top» in Linux).

Description:
Hello,
I'm using gmp library to perform a function which uses a few
operations with large integer values. My script runs in console mode
(at least four hours of processing), scanning a big mysql table and
invoking the function to calculate big integer values that are stored
in the table.
But, in case the table has a lot of rows to process, the script halt
with 'out of memory' error. Studying the problem I realized that GMP
functions didn't free memory (when I issue unset( resource ) ) and
continue allocate memory in every function pass. There is no gmp_free()
in php manual.
Is there any workaround to avoid the problem?
Thank you,

Reproduce code:
---
for( $i = 0; $i = 100; $i++)
store_calc_value( $i );
function store_calc_value( $v )
{
$a = gmp_mul( $v, 0x1 );
$b = gmp_mul( $a, 0x1000 );
$sql = Insert into t (big, value) Values (;
$sql.= gmp_strval( $a ) . , . gmp_strval( $b ) . );
mysql_query( $sql );
unset( $a ); // gmp_free( $a );
unset( $b ); // gmp_free( $b );
}
Expected result:
I expect that memory has to be freed once returning from function
store_calc_value(). A simple top command in another Linux session, tell
me that php resource continue to grow.
