[Tinyos-help] Problem: simulation terminated unexpectedly

[Eva Maria Garcia]

Hi all!

 

I am simulating my application in TOSSIM 2. This application sends and
receives packets from all the neighboring nodes. When I simulate it, I get
the next error in gdb python:

 

Program received signal SIGSEGV, Segmentation fault.

[Switching to Thread -1210013504 (LWP 8097)]

0xb796039d in TossimActiveMessageC__Model__receive (msg=0xb79d8266) at
/opt/tinyos-2.x/tos/lib/tossim/TossimActiveMessageC.nc:105

105         memcpy(bufferPointer, msg, sizeof(message_t));

 

 

And the stack trace I get is:

Please, can anybody help me?
