./waf --regression reports that:
Command ['/home/raj/code.nsnam.org/ns-3-dev/build/debug/examples/tcp-nsc-lfn',
'--ns3::OnOffApplication::DataRate=40000', '--runtime=20'] exited with code -11 

Running in GDB gives the following backtrace.  Can anyone reproduce?

(gdb) set args --ns3::OnOffApplication::DataRate=40000 --runtime=20
