Error in dev3 test

[andresailer]

I am trying to figure out if this is caused by the changes in DD4hep, or root...

Failure is because "Exception" is found in the log
https://github.com/AIDASoft/DD4hep/runs/2183002592?check_suite_focus=true#step:4:4630

Not clear why this is printed now.

[andresailer]

For reasons that I don't understand a fraction of some file is printed at the end of this test
https://github.com/AIDASoft/DD4hep/runs/2183002592?check_suite_focus=true#step:4:4630

     /// Access the bound data payload. Exception id object is unbouna

With the addition of 4 std:: from #797 the word 'Exception' is now fully part of this printout

[andresailer]

This also happens, for example in LCG_99 (root 6.22.06) and for all the AClick tests in some form or another. (Maybe also others 🤷 )

[MarkusFrankATcernch]

Isn't this normally an artifact resulting from missing ROOT dictionaries, which cannot be compiled on the fly ?
Though, this usually does not happen at the end of the job...

[andresailer]

yes, usually if there is this printout is because something went wrong with finding header files. But then the whole "file" is printed out, not some "random" fraction of it. But everything seems to work.
Running valgrind now...

[andresailer]

So I think this is an issue with (how we call?) Geant4
at the very end of the execution valgrind reports:

I.e. some issue with the d'tor of G4strstreambuf
https://gitlab.cern.ch/geant4/geant4/-/blob/geant4-10.7-release/source/global/management/include/G4strstreambuf.icc#L46

When I LD_PRELOAD that implementation,

with

class G4strstreambuf {
public:
   ~G4strstreambuf();
}; // Class
G4strstreambuf::~G4strstreambuf() {
    std::cout << "@@@ Replacing StreamBuffer DTor @@@" << std::endl;
}

g++ -shared -FPIC -o libPreloadBuffer.so preloadBuffer.cpp

and LD_PRELOAD=./libPreloadBuffer.so

The issue goes away.
