Hi, Updated patch, rev 3. Overloaded gethashseed() in a few classes which I missed before. Also modified gethashseed() to use "fast" hash for derived classes which do not overload it and made it independent of mangling scheme for non-template classes. Removed some debugging output. IMO "fast" hash can be removed entirely and if classes do not overload gethashseed() it will be taken care of by typeid. But since it is relevant only for custom user-defined classes, I don't care much. I kept it because GiNaC developers seem to have sentimental attachment to it. Best, Valery PS patch chunks have only 1 context line, because this list has post limit of 40kB With best regards, Mr. Valery Yundin. On 25 May 2014 18:44, Valery Yundin <yuvalery@gmail.com> wrote:
