Description Daniel Vrátil 2012-11-13 23:26:30 UTC

Application: kdevelop (4.4.60)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.6.6-3.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
KDevelop crashed when I finished the "New Class" wizard without creating the class.

The crash happens only when using the "New class" wizard for the second time. After restarting KDevelop, I can create a new class without any problems. Creating one more class crashes KDevelop though.

This happens with recent git master.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Daniel Vrátil 2012-11-13 23:29:34 UTC

To be more clear: KDevelop crashed when I clicked "Finish" on the last page of the "New Class" wizard and respective .cpp and .h files were not created by KDevelop before the crash.

Comment 2 Milian Wolff 2012-11-30 15:56:44 UTC

Git commit d051357753220b47d1e5105850b3cd5038ec4b63 by Milian Wolff.
Committed on 30/11/2012 at 16:47.
Pushed by mwolff into branch 'tabbed-filetemplate-preview'.

Create a singleton TemplateEngine that owns the Grantlee engine.

Grantlee tries to unload plugins when the engine is unloaded which
is hazardous and can lead to random crashes.

This also makes more sense from the API point of view since the
engine should not have a 1to1 relationship to a Grantle::Context.
Instead, that should be a 1toN relationship.

I have a bad feeling though: The ArchiveTemplateLoader, which get
registered to the Engine, store a raw KArchiveDirectory* pointer
which will probably be invalid as soon as the KArchive gets destroyed.
This just begs to break down eventually, yet I do not see a way to
unload a template loader from Grantlee. Probably we should refactor
the ArchiveTemplateLoader to reflect its temporary nature. I think
a RAII pattern should work, paired with a single ArchiveLoader in
the engine that supports multiple archives registered by the RAII
class.

Anyhow even without the above this patch seems to resolve the crahes
in the new tabbed file template preview. Many thanks to Olivier JG
for investigating this issue!
