Dear everyone,
I tried to do simulation with the semantic queue in ns2.26. I changed
nothing in ns2 original code. I set PacketQueue/Semantic in the tcl
script, but got the segmentation fault. By using gdb, i got the
following report for error:
Program received signal SIGSEGV, Segmentation fault.

Could anybody tell me where's the segmentation fault?
Your help is highly appreciated,
