Hello everyone !
I met a weird problem and I found that some people have discussed
it in the mailing list before. Unfortunately, their comments cannot
help much so that I post it again.
My program attempts to inspect the communication among 9 nodes.
There was no error while compiling as shown below.

However, when I ran the program, I got following output:

Segmentation fault (core dumped)
I also added some DBG message in StdControl.init and
StdControl.start, however, none of them showed up.
Can anybody tell me what might be the reason?
Run TOSSIM in gdb.
Thank you very much!
PS: The footprint of the program is around 21KB -- I noticed that
some people said that exceeding 16KB would sometime trigger the
"Segmentation fault", I don't know whether it could be a reason for
it.
No.
