a) It hasn't the function names for the NS proc (as it has for tcl procs)
Is ns2 stuff compiled for debugging? (-g gcc option)?
b) use DDD and valgrind

Subject: [ns] Issues debugginf ns-2.29
Hello Every one,
I made some modification to the ns-2.29 and was running my new
version. But after running for some time it crashes leaving the
following information. I was wondering if any one has suggestion about
to make use of the following information to debug ns-2.29.
*** glibc detected *** ../ns: corrupted double-linked list: 0x00c1d8b8
