Description

Running some old sotest scripts with SCTP I get an ASSERTION failure (ASSERT(0))
../../common/inet/sctp/sctp_timer.c line 661
The sctp_t is in state -4 (SCTPS_BOUND)
Reproduce by
bobo[1] cd ~nordmark/ws/test_ws/api/sotest
bobo[2] runall.csh.sctp
This worked fine in snv_57.
I observe the panic on snv_63.
The sctp_t is below:
