-- Information about the crash:
I'm usint git master of the kdevelop. Today build crashes because of failed assertion less then minute after start. It's 100% reproducable for my session containing only two projects available here: https://gitorious.org/mahjong-night

The following output is provided:
ASSERT: "range.start > childContexts.at(nextContextIndex() - 1)->range().start" in file /home/vestnik/Development/install/include/kdevplatform/language/duchain/builders/abstractcontextbuilder.h, line 615

kdevplatform: 4ad75b0c0e1bf0a29bdaa4aacf7aa14a6e8c70f1
kdevelop: d5c9aa663f333d38a0a8e8a68dd24d233b4f8817
All other dependencies are installd in the system (up to date Arch Linux packages).

The crash can be reproduced every time.

Hi,

I have the same problems. I imported kdevplatform and kdevelop as projects. The crash happens also every time.
Comment 2 Bastian 2011-06-07 23:32:58 UTC

rm -rf ~/.kde4/share/apps/kdevelop/sessions/*
rm -rf ~/.kde4/share/apps/kdevplatform/sessions/*
temporary solves this issue. However Kdevelop crushes on this assert again when I use quick open, Ctrl+Click on symbol. Once failed it always fails after restart.

Git commit 7e189d35e4a5d207b0711610114cae481f6497e5 by Milian Wolff.
Committed on 08/06/2011 at 18:23.
Pushed by mwolff into branch 'master'.

Revert "add assertion for misuse of AbstractContextBuilder::openContext"

This usage is apparently sometimes used in the CPP lang plugin,
I have to investigate whether it's a bug there or whether
it depends on this usage implicitly, maybe as requirement for
contexts in macro expansions...

To unbreak master, lets revert this for now.

This reverts commit b494fac2293237ab095f040cace27b7f3e899d80.
