After upgrading from ns-2.33 to ns-2.35, every ns2 run ends with the message:
Aborted (core dumped). My first ns-2.35 installation was on cygwin 1.7.13-1 and WinXP Professional SP3. Now I'm seeing the same behavior with cygwin 1.7.20-1 and Win7 Enterprise SP1. The following is a gdb backtrace from running a very simple script (found here: http://blog.eviac.com/2012/11/ns-2-simulation.html). Any idea about causes/solutions? -- Andrea Program received signal SIGABRT, Aborted. 0x6c9f00d7 in Tcl_Exit () from /home/francini/ns-allinone-2.35/ns-2.35/libns.dll (gdb) backtrace #0 0x6c9f00d7 in Tcl_Exit () from /home/francini/ns-allinone-2.35/ns-2.35/libns.dll #1 0x00289240 in ??
