[serialization] Assertion `new_cid == cid' failed - fails on gcc, works on msvc

Hi, I am serializing/deserializing a polymorphic class and I am having the above issue upon deserialization where it fails on gcc and works in msvc. The serializer and deserializer are implemented in two different executables. Should that be an issue? All the object files *except* the serialize/deserialize/main functions are the same in both executables. In the gcc case, its comparing new_cid=2 against cid=1 (if that helps at all!) TIA, Sohail

Ok to rule out the different executables being the issue (thought typeid might be the issue), I've made them into one executable. Still no difference though. -----Original Message----- From: boost-users-bounces@lists.boost.org on behalf of Sohail Somani Sent: Mon 3/26/2007 9:13 PM To: boost-users@lists.boost.org Subject: [Boost-users] [serialization] Assertion `new_cid == cid' failed -fails on gcc, works on msvc Hi, I am serializing/deserializing a polymorphic class and I am having the above issue upon deserialization where it fails on gcc and works in msvc.

Things to try: a) does it work with non-polymorphic archives of the same type: binary? etc. That is, can you check to see if its an issue with "polymophic-ness" or not. b) try serializtion to xml_oarchive and save the output. check to see that you can read it. Then try polymorphic_xml_oarchive and compare the two. Robert Ramey Sohail Somani wrote:

Hi Robert, Thank you for your response. In my example, the archives are not polymorphic, the class I am serializing *is* polymorphic. I think I've narrowed it down to stripping out the use of shared_ptr (i.e., without it, it "works") but I'm going to try for a smaller example. Sohail

Ok I got a bit further on this. In the example I attached earlier, if I make the base class non-abstract and remove the BOOST_IS_ABSTRACT(base) specialization, it "works". However this will kill the use of serialization for me :-( Is is_abstract<base> interacting in a mean way with shared_ptr?

[xml output for vc71 and gcc32 snipped] If I load from the archive in gcc32 using the xml string from vc71, it works. So it seems that for some odd reason, gcc is generating the wrong id's to begin with.

From Visual C++ 7.1:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <px class_id="1" class_name="derived" tracking_level="1" version="0" object_id="_0"> <base class_id="2" tracking_level="0" version="0"></base> derived id </px>

shared_ptr addresses are not tracked since one isn't serializing a pointer to a shared_ptr. So this is OK. What I see is that on the gcc output, we're "skipping" a class id. This is not what I expect to see. I looked into the code basic_oarchive.cpp where classes are tracked. I suspect this would be tracked down to something in the extended_type_info registry which isn't properly keeping track. Basically one would have to dive in with the debugger with your test.

Currently I only have the HEAD and RC_1_34 on my system and can't run a gcc test. I did build and compile and test with vc 7.1 and found no problems.

Try serializing your test to xml archive. That will make the details a lot more visible.

Thought you might like to know that the test I attached before works fine under gcc 3.4. Might need to put a note about gcc 3.2 somewhere? I still don't know what the real cause is. Thanks for your suggestions! Sohail
