make: *** [r213] Segmentation fault (core dumped)

[Thorben I.]

Hello,

I got a problem with "make: *** [r213] Segmentation fault (core dumped)".
I start a number of 500 simulations. Everything is working fine but at some point the simulation crashes with this error message. But its not the same number of simulation everytime. Sometimes it's crashing much earlier but I already had one simulation where all 500 runs completed without problems.

Do you have some hint on how to find out why the crash occurs?

[Thorben I.]

I really need your ideas. I solved every memory leak caused by my code with use of valgrind and I don't know what to do. Last test run 5 crashed...

As far as I see the error mainly occurs on a virtual server machine.

I spent some time to debug and to inspect the core dump file:

As I see the seg fault occurs in some methods that I don't know...
Somebody got an idea?
