Hi Laruence,
Thank you for sending this.
I'm not sure if the patch is completely correct.
With the patch all the threads share the single copy of script_encoding_list and when one thread terminates it calls compiler_globals_dtor() and frees the script_encoding_list. But other threads still keep reference to it.
I think we have to duplicate script_encoding_list for each thread in the same way as we do for CG(function_table).
Also I noticed a related issue. At zend.c compiler_globals_dtor() CG(script_encoding_list) deallocated using free() and in zend_multibyte.c zend_multibyte_set_script_encoding() using efree().
I suppose the second place has to be fixed.
I would appreciate if you could look into the problems.
Thanks. Dmitry.
