[ns] Infinite recursion/Seg. fault...

[Anders Lindgren <dugdale@sm.luth.se>]

Hi,

I've been running some simulations which require rather much memory. When
the number of nodes and the amount of traffic was increase "too" much, my
simulation got a seg. fault, so I checked it using gdb, which told me the
seg. fault was in malloc and gave me this stack trace:

#25176 0x804a26a in abort ()
#25177 0x813a323 in __default_terminate () at gen/ptypes.cc:116
#25178 0x81383ad in terminate () at gen/ptypes.cc:116
#25179 0x8138455 in __eh_alloc () at gen/ptypes.cc:116
#25180 0x8137dee in __builtin_new () at gen/ptypes.cc:116
#25181 0x8137c40 in __builtin_vec_new () at gen/ptypes.cc:116
#25182 0x8133a15 in Tcl::evalc () at gen/ptypes.cc:116
#25183 0x804a26a in abort ()

The above lines are repeated in eternity it seems (as you can see, I'm
25000 levels down the stack trace, and there are still more to go). 
It seems like something happened that caused me to end up in an infinite
recursion or something like that.

Has anyone else encountered similar problems?
