Hi, Using the recent Fedora 18 release, I noticed this is not possible to update a stock ASN1 object anymore. This is because const objects are now stored in read-only storage. The nid_objs[] table is such a const object, and a pointer to an entry of this table can be returned by OBJ_nid2obj() as an ASN1_OBJECT * value, without the const. Thus it is not possible anymore to modify a stock object. It is not possible either to duplicate it (for later update), since OBJ_dup() does NOT duplicate static objects. If this feature is intended to be supported, the nid_objs[] table should not be a const. Else the OBJ_nid2obj() result value should be a const (to detect problems at compile time). Or maybe some info about this should be added to the documentation. As an example, please find a demo program in attachment: if executed on a system that stores static const objects in read-only storage, you'll get a segfault. Else the stock object short name is updated. Thanks for your attention Patrick
