To be honest I'm passing the return_value into my recursion - is the same true of it? I ask because I watched my memory consumption climb to over 500MB and all I use is MAKE_STD_ZVAL( newVar ) and insert into some depth of the recursion initially stored into return_value for the calling function. My initial assumption was that indeed this stuff is garbage collected... but maybe I'm doing something wrong if this is collected at the moment of overwrite and I'm seeing such massive allocations using top.
