Kalarm is working OK. I have not seen any problems for quite a while.

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test
if the bug is valid in the latest version? I am setting the status to NEEDSINFO
pending your response, please change the Status back to REPORTED when you
respond.

Thank you for helping us make KDE software even better for everyone!

https://bugs.kde.org/show_bug.cgi?id=356940

--- Comment #16 from Martin Sandsmark  ---
The issues in the bug I linked to is an application exiting before the the
QCoreApplication destructor is run, which is not supported by Qt. A heap
allocated QApplication is just one possible way for that to happen, another is
to call exit() with a stack-allocated Q*Application in main() (as most people
do).

See e. g. the discussion here: https://git.reviewboard.kde.org/r/127626/

The biggest problem is that the design of e. g. QCommandLineParser and
KDBusService depend on calling exit(). I have discussed some solutions and
hacks with thiago about it on IRC, but I haven't come up with a proper
solution.

The linked issue is different, its root cause is heap-allocated QApplication
that is not deleted early enough. If I modify the ASAN testcase, then it will
indeed fail randomly:
make: Nothing to be done for 'first'.

Extended the testcase to do normal QApplication::quit(), the proposed patches
would still result in a crash for that case. Better rip this delete hack

Adding David (Edmundson) since he did something similarin this area
(https://git.reviewboard.kde.org/r/122184/).

Can the title be changed to something like "Applications using QProxyStyle
crash on exit()".

Wireshark actually used setStyle(), passing an extended version of QProxyStyle
that follows this example: https://doc.qt.io/qt-5/qproxystyle.html#details.
With this patch, the crash no longer occurs:

Adding David since he introduced the fix that is referenced in the breeze code:

commit 2ffe20e1bfe93c921c5372b4d21447b1de308d4b
Author: David Faure 
Date:   Sat Jun 7 14:57:29 2014 +0200

Fix crash on exit in all QCommandLineParser-based programs.

Example: kioclient5 ls  (= a syntax error).

The issue is that ::exit(1) is called, so ~QGuiApplication isn't called
(so the style isn't deleted), but global static objects are deleted,
which deletes the style-plugin-factory, which unloads the style plugin.

The crash happened because "AppEventFilter" in oxygen would still be
installed as an app event filter, but the plugin was unloaded, so any
calls to it would crash.

If I disable the delete hack or avoid calling delete for the second attempt
(likely wrong approach...), then the crash is gone. Was this a workaround for a
specific Qt version?

Created attachment 100758
  --> https://bugs.kde.org/attachment.cgi?id=100758=edit
Testcase (with ASAN)

I bisected Wireshark and found that it started crashing after using
setStyle(new QProxyStyle). Fair enough, I can create a minimal testcase that
crashes when setStyle(new QProxyStyle) is used and exit() is called.

This problem does not occur when -style windows (or anything other than breeze
and oxygen) is in use.

Following test was done with:
qt5-base 5.7.0-2
breeze v5.7.4-17-gf79266d (also reproduced with 5.7.3-1 and many releases
before that...)
oxygen 5.7.3-1 (not in output, but also affected)

ASAN output:

With Breeze 5.6.1 + f56b8b9fbe97f83cf18523dde3a1f83fada9beab, I sitll manage to
crash an application on exit. To reproduce, start "wireshark -O foo" (this is
an invalid option, resulting in exit() after the QApplication is constructed,
but before exec() is called.

(Qt version 5.6.0, Wireshark from git, but also reproduced with any stable 2.0
version)

[Breeze] [Bug 356940] kalarm crash on start up

2016-03-30 Thread Hugo Pereira Da Costa via KDE Bugzilla 
https://bugs.kde.org/show_bug.cgi?id=356940

--- Comment #5 from Hugo Pereira Da Costa  ---
Git commit 32746a734d2825f76ddaaa903f6c80ceaa40a28f by Hugo Pereira Da Costa.
Committed on 30/03/2016 at 13:41.
Pushed by hpereiradacosta into branch 'master'.

Create animation "on demand", that is, when there is at least one animated
progressbar.
Delete it when all animated progressbars have stoped or have been unregistered.
This prevent the underlying QPropertyAnimation to be deleted "too late" after
an application was exited,
which in turn sometimes result in a crash
changes. Lines starting # with '#' will be ignored, and an empty message aborts
the commit.

Hi, 
thanks for posting the simple test case.
I can reproduce the crash with qt5, (but not with qt4).
Will investigate.
