issue in copying the hash table(Reposted third time)

Hi All, Sorry to repost for the third time. I want the clarification regarding copying the global_class_table to thread specific compiler_globals->class_table in compiler_globals_ctor in Zend/zend.c. According to me memcpy should copy 'whatever source points to' to 'destination'. Our class_table hashtable structure looks like this, char *key; zend_class_entry** value; So memcpy should copy only whatever (zend_class_entry**) points to which is semantically wrong good candidate for Segmentation fault. No way memcpy can do double dereferencing for this case. Somehow in Linux when i compile it with maintainer-zts-mode memcpy copies the data fine. I verified all the internal classes. Thread specific class_table is in sink with the global_class_table. Please clarify. Thanks in Advance With regards Kamesh Jayachandran
