Dear Bernhard,
Thank you for your investigation and your time. You are right about
these double delete and this will have to be fixed.
But I am still puzzled:
1) your patch is absolutely required for handling delete properly (btw
thanks for the corresponding references!) but unfortunately it can fix
only some of the tests
2) this bug only appeared recently, no segfault were detected before on
sid (first trace I found of a failure is in our weekly packaging test
last Sunday 15 September, everything was fine on Sunday 9 September)
3) the segfaults are generated during testing
This probably means that the problem comes from a deeper (darker, harder
to find) side of the build.
So I started with the first test on the list that generates a segfaults
(test #27 named action-editframes-level1-1) and run it through the
debugger (I run it through the same xvfb-run command line as in the
debian/control file).
Here is the first outcome:
xvfb-run --auto-servernum --server-args="-screen 0 1024x768x24"

It is very strange as this specific call to vtkTextProperty::ShallowCopy
never generated a segfault in any version of the code. Is this a problem
linked with X11/OpenGL?
This is where I am at the moment, nothing solved at all, but I wanted to
let you know of this findings.
I suspect something changed in one of the dependencies that generates
this. I tried to check which package was modified recently and might
have influence this. I found that xvfb might changed recently and I am
currently rebuilding with an older version installed to checked (but
that looks like groping my way along!)
Andreas, do you have any smart way to check the list of packages that
have changed/been uploaded in sid in the dependencies of a package
during a period of time (here from 9 Sep to 15 Sep)? This might help me
finding how to solve this.
Thanks for your help again and hopefully this will be tackled down soon!
