using hash_find for objects ?

hey all, i'm really hoping someone can tell me where i'm being braindead.. I have this function that takes in an object, and this object contains other objects. specifically, the tree looks like this: $start->year=1999; $start->month=8; $start->mday=28; $start->hour=0; $start->min=0; $end->year=1999; $end->month=08; $end->mday=29; $end->hour=0; $end->min=0; $event->start=$start; $event->end=$end; $event->category = "category"; $event->title = "title"; $event->description = "description"; icap_store_event($stream,$event); So, now i'm trying to pull in the $start and $end parts of the object... heres the code snippet that tries to pull out the $start object, and traverse down it: (note, storeobject was one of the initial function parameters, and i previously called convert_to_object() on it. if(_php3_hash_find(storeobject->value.ht,"start",sizeof("start"),(void **) &temppvalue)== SUCCESS){ SEPARATE_ZVAL(temppvalue); convert_to_object(*temppvalue); if(_php3_hash_find((*temppvalue)->value.ht,"year",sizeof("year"),(void **) &pvalue)== SUCCESS){ SEPARATE_ZVAL(pvalue); convert_to_long(*pvalue); myevent->start.year=(*pvalue)->value.lval; php_printf("year is %d<br>",(*pvalue)->value.lval); } This aint working though: 780 if(_php3_hash_find((*temppvalue)->value.ht,"year",sizeof("year"),(void **) &pvalue)== SUCCESS){ (gdb) next Program received signal SIGILL, Illegal instruction. 0x81179e9 in ?? () Can anybody please give me a clue?! Thanks! Mark
