Crashes when closing app

General
1

Recently I noticed my apps (three different apps) crashes sometimes when you close them. Not sure with which Xojo release this was introduced.
It doesn’t happen always though … seems ‘random’.

All Crash reports always referring to NAAutoReleasePool

Any clues?

2

This might mean that an Objective C object has been released manually, which leads to a crash when the auto release pool wants to release it.

3

You can only find which steps cause a crash most of the times.
Could be a declare, plugin or framework method which releases and object once too often.

See
https://developer.apple.com/library/ios/documentation/DeveloperTools/Conceptual/InstrumentsUserGuide/EradicatingZombies.html

So you could maybe find the object over released.

I am forcing to release NSProcessInfoActivityMBS in the CancelClose event ( token=nil).
I do this in those three apps. Maybe that could be the issue.

Will remove the NIL and see what happens.

6

the activity doesn’t look like something in an array…

7

It wasn’t the nil issue. I still get the same crashes at random.

9

Found why it crashes.
Whenever I call in the Window CancelClose event:
ProcessInfo.endActivity(token)

BTW ProcessInfo = NSProcessInfoMBS.processInfo

It crashes 1 out 5 times.

We’ll look into it.
The code is here very careful to not overrelease it, but maybe you found a way.
(or Apple has a bug)
