Please test the exact thing I suggested :) var_dump(memory_get_usage()); token_get_all(file_get_contents(<FILE>)); gc_collect_cycles(); var_dump(memory_get_usage());
memory_get_peak_usage() is irrelevant, and USE_ZEND_ALLOC won't give accurate results anymore when looking at memory usage. If the above gives the same numbers you got initially, then there's a memleak in token_get_all().
