Hi MVD experts,
as agreed during the last EVO meeting, I updated the code to the last revision and re-run the reconstruction on my files to see whether the crash happens or not.

Unfortunately I still see the crash on PndRiemannHit::operator<.

In my previous message on this thread I found a connection between this crash and an uninitialized variable (fS, in PndRiemannHit).

Even if you don' t see the crash, can you please check this variable by putting a cout (std::cout << "s() " << s() << std::endl;) in the function:
bool operator< (const PndRiemannHit& aHit)
of PndRiemannHit.h to see if you see something strange too?

I see something like:

s() -1.174e+14
s() -1.174e+14
s() 1.196e-224
s() 1.196e-224
s() -1.174e+14
s() -1.174e+14
s() 1.196e-224
s() 1.196e-224
s() -1.174e+14
s() -1.174e+14
s() 1.196e-224
s() 1.196e-224
s() -1.174e+14
s() -1.174e+14
s() 1.196e-224

and these are clearly weird numbers.
Thank you in advance,
Lia.
