Re: Trying to find out where the memory went
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().
