Comment 1 Milian Wolff 2011-01-31 12:35:40 UTC 
I've seen this assert before, but never in association with one of the assistants. anyways, we need to fix this somehow.

David, and clue what might be going on?

Eric: unrelated to this bug report, put it into a new one. And I don't see how a foreach() can possibly crash o_O

*** Bug 267132 has been marked as a duplicate of this bug. ***
Comment 7 Milian Wolff 2011-08-28 13:12:34 UTC 
/me wonders whether this could simply be an issue due to a corrupted .kdevduchain cache and hence only occur once and then be gone since the cache gets wiped after two consecutive crashes...
Comment 8 Milian Wolff 2013-12-01 16:24:06 UTC 
*** Bug 318046 has been marked as a duplicate of this bug. ***
Comment 9 Milian Wolff 2014-08-08 14:21:26 UTC 
With kdev-qmljs completion test, one can now reliably trigger this assertion - so let's hope I can debug it and fix it.

OK, I finally figured out the reason for this bug, the fix is not yet clear to me, lets see.

1) we create a QID and store its Indexed form in memory
2) since we never serialize this item it never plays a role in the on-disk refcounting
3) on shutdown, globalItemRepositoryRegistry().finalCleanup() is called in DUChain::shutdown
4) later in that function, sdDUChainPrivate->doMoreCleanup(); and sdDUChainPrivate->clear(); are called, the latter of which will again call doMoreCleanup
5) eventually in-memory DUContexts will get unloaded, if they happen to have an IndexedQID stored which was cleaned up (since it never was serialized, its refcount was not increased), we will access a deleted item in the itemrepo

-> havoc.

Created attachment 88184 [details]
add additional debug code to identifier.cpp

this patch is too ugly for me to add to the codebase, but I don't want to loose it either so here it is attached (it helped me figure out whats going on here).

Git commit 5d1e162f4b624be896efb9dad8e952d9596f8424 by Milian Wolff.
Committed on 09/08/2014 at 17:29.
Pushed by mwolff into branch '1.7'.

Delay final cleanup of DataRepositories until end of DUChain shutdown.

This is required, as otherwise non-disk-refcounted items might get
deleted but then later-on accessed again. This is a reason for
random crashes during shutdown, which only occur for complicated
DUChain structures. Only then would further cleanup happen after
the call to ItemRepo's finalCleanup, and DUContexts still lie
around in memory...

Thankfully we had a reproducible test case with the code completion
unit test in kdev-qmljs (master) which is fixed by this patch.
Logically, I'm also confident that this is the correct approach.
