Simulation terminated with exit code: 139

[Anna]

Hello!

I've been working on my project in OMNeT++ 4,1, everything is great...
except this error that bogles me:

Simulation terminated with exit code: 139.

I know, I know... It's been written about before. It appears in
different moments of the simulation, not all the time, but very often
lately, and exits the simulation. I have searched online for info on
it and I know it has to do with segmentation faults (memory problems,
right?), but I don't know how to fix it. I installed Valgrind and did
a memcheck with leak-check. There were 60 errors, but all of them came
from the C libraries. I have read in the Valgrind manual that such
errors are likely to appear and, of course, I have no business
changing the C library code.

I thought that maybe I have some mistakes when working with my
classes, not destroying objects when I'm done with them. Is it true
that I have to call the destructor myself, doesn't it jump in by
itself at the right time like in Java? Also, I did call the
destructors to see if this was the problem, but the exit code still
happens.

Can you give me some advice? I'm getting kind of stuck...

Thank you

I forgot to mention, I also tried to increase the Linux stack size to
256MB and set the total-stack parameter in my simulation to 200MB, but
it still doesn't work.

Hi,

Segmentation Fault means that your code tried to access an invalid
memory address, most times this comes from accessing an already deleted
pointer somewhere in your code.
The best tool to find the place where this happens is a debugger like
"gdb" under linux from the command line or the debugger from the omnet IDE.

Regards,
Karl

I get this error every time i close a simulation. Even with the INET samples.

The simulation runs well then i stop and close it, when i ruturn to the IDE i see on the console "Simulation terminated with exit code: 139".

I'm running omnet on a 64bit linux pc.

Can anyone suggest some good tutorial on how to use the debugger from omnet++ ide.  I am unable to understand how to trace in which line of my code the segmentation fault is occuring.

You can use any eclipse tutorial

http://download.eclipse.org/tools/cdt/docs/tutorials/debug_tutorial/cdt_w_debug.htm

 

also you can consult the manual

http://omnetpp.org/doc/omnetpp/userguide/index.html
