on MITK master:

This is still inconsistent, see screenshots:

Speculating:
Maybe that was a bash environment side effect, i cannot reproduce this error on my GNU/Linux system where I use tcsh instead of bash.
The tcsh environment does not contain anything "conda" related, while bash does, if (ana|mini)conda is installed.

Same bug with alternative build configuration:

Ich sah hier was ähnliches, beim MITK bauen auf meiner ubuntu-OpenStack-Instanz, allerdings ohne Anaconda, mit gcc 7 (g++-7/gcc-7 version g++-7 (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0): undefined reference to `ucnv_convertEx*'

Pushed new branch T26385-remove-undeclared-function-from-QmitkFiberQuantificationView.cpp.

Does not crash anymore, but the network node's balloon info text remains visible and unchanged, sticking to the world geometry even after deleting data node in the Data Manager.

Someone fixed it, thanks.

Underlying geometry problem seems to be fixed, cannot reproduce this bug anymore.

I cannot find those names in ep/src/DCMQI (d067f81c8a8e43900b91861f771013406868672f) or DCMTK, either:

git-grep in the actual master (c4445dc0ce19d9e3b3c0bb930ee84543aed4e5b2) shows only one match:

Pushed new branch T26384-fix-misleading-inidentation.

You mean like

-Wno-error=catch-value=

I ran into the same problem on Debian/Gnu Linux, on both "buster" and "sid", i.e. testing and unstable, using g++ (Debian 6.3.0-18+deb9u1) 6.3.0 20170516 compiler.

Awaiting code review by O1.

In hindsight, operator== didn't fail at all and remains unchanged, besides some cosmetics to debug messages.

There where 2 UpdateStatusBar() functions m)

Hmm, the exception "ERROR: Unhandled excaption caught in ExecuteAction(): /home/mhettich/MITK/Modules/Core/include/mitkImagePixelAccessor.h:89: Invalid ImageAccessor: PixelTypes of Image and ImageAccessor are not equal." now only happens on clicking on the image in the StdMultiWidget, NOT when navigating via the ImageNavigationView

Maybe from QmitkImageNavigatorView::UpdateStatusBar() Line 263 ?

Pushed new branch T22510-ImagePixelAccessorPixelTypesComparison.

crashes in different ways or at different points within the vtk rendering chain, but always after repeating this user action, and not on the first time.

not complete yet: T22342-fix_vtk_rendering_crash_in_connectomics_balloon_help.

Pushed new branch T22342-fix_vtk_rendering_crash_in_connectomics_balloon_help.

Here the backtrace:

see also T20227

GUI shall present a clickable matrix (from,to) and a action button which shall produce a new fiber bundle with only the selected fibers.

Seems to work now in master, commit bfcf1f07676058b32bee39f295ea1019013943ec

Thanks
works now fine.
