In berryXMLPreferencesStorage.cpp:99, opening of the preference file crashes:

f.open (this->m_File.path().c_str());

Where path is "C:/Users/Stefan/AppData/Local/DKFZ/MITK Workbench_2871227531/data/5\\prefs.xml"

I guess the "\\" might be a potential candidate, as the file does exist.

Okay, it's not. This code is called several times during application and it works every time. Even on application shutdown it works the first time and then fails (see stack trace above).

Next step is to see if it fails on Linux at this function of the standard library too:

liborg_blueberry_core_runtime.dll!std::basic_filebuf<char,std::char_traits<char> >::_Initcvt(const std::codecvt<char,char,int> * _Newpcvt)

Debug output at application shutdown:

Only switch locales for MSVC.

Still happens on MSVC 2013 Update 3 with MITK Superbuild and QT 5.4.

#ifdef in line 88 is parsed and locale is switched to std::locale("") but debug error from xstring.h (string iterators incompatible) still is thrown.

((changing status to unconfirmed on MSVC 2013 Update 3 )) as reported recently

On which system was the fix verified?
Please tell me if I can assist anyhow.
;) Ingmar

This is a slightly different issue which is not directly related to the fix above, but I guess it fits into this bug description anyways. :)

I already debugged the issue you just reported last week. It turned out, that it probably has something to do with library unloading and/or the undefined order of cleaning up global variables.

The very same code path works multiple times during startup and the first few times on shutdown sometimes. Poco uses an internal global const std::string called EMPTY_STRING which is used to be able to return a reference to an empty string from any function. At some point during application shutdown, this container (string) is obviously not valid anymore (the container reference of the iterator in question is 0). This is a special case when checking whether iterators are compatible (meaning that iterators have the very same container as reference), which is also true for two dangling iterators even both references are the same (0).

I guess this one is quite tricky to fix. Any ideas / help is appreciated. ;)

BTW this issue does not occur in Release mode as the checking of iterators is only done for a higher value of _ITERATOR_DEBUG_LEVEL. If you quickly need a workaround, lowering this value in debug mode could be a temporary "solution". Note that I put solution in quotation marks, I know that this is not a true solution. :)

A first attempt for a true solution could be to check if Poco is really in an unloading/unloaded state when this bug happens and to find out then how we could defer unloading.

;) absolutely agree!
And yes, _ITERATOR_DEBUG_LEVEL would be a temp solution... but it's not that urgent.

I postponed it so long on my side as I am currently working on IO. Will probably come back to this next week but by low level skills are not that good, I guess!

Have a nice weekend,
Ingmar

With the latest changes of BlueBerry, both(!) issues descriped in this bug do not occur anymore. However, the integration of the BlueBerry changes is not yet complete which is why I cannot recommend to update to the latest master right now.

Great and good to know. Is there a rough schedule when the feature will be finished to integrate the bugfix into the master? Or is there a way to isolate the bugfix only?
Best, Ingmar

Next week when Sascha is back it will be finished.

I said I wouldn't recommend to use the current master mainly because the Workbench didn't run in Release mode and the Packaging doesn't work currently. Meanwhile, without changing anything, both debug and release mode works for me. But (there's always one, isn't it? :]) Marco still have the string iterator issue in his VM. So... maybe some race condition is going on here and it is not really fixed. sigh

Would be great if you could run an off-side debug-and-release build of the current master (maybe over night) and report what's going on on your side during startup/shutdown of the Workbench both in debug and relealse mode?

Sure! So I have updated to the current master (96ce992e5d1e51dba0aabe1541af9a7a145d9eba) and configured and generated cmake (not a complete superbuild rebuild yet).

There is an additional output message in the console:
1.19 blueberry.ui..wrkbncPlg: LOG: org.mitk.gui.qt.extapplication: Invalid intro binding. introId and productId must be defined

Release: start-up, loading stl and nrrd files, closing works fine, no crash.

Debug: start-up, loading stl and nrrd files, closing works fine. No crash during shutdown.
Additional message in console: 6.92 blueberry.core.Commands.commandtracing: HANDLERS >>> Command('org.blueberry.ui.views.showView') has changed to 'berry::ShowViewHandler' as its handler

;) Looks good!

Thank you for testing. That's exactly what I see on my machine as well.

Is this still an issue?

Removed 2015.05.02 target milestone as this bug was resolved before 2015.05.
