[Lksctp-developers] setsockopt(SCTP_EVENT): Invalid argument

[Song S. <son...@gm...>]

Hello,
     I've come across a problem when use lksctp test-tools,after running the
command "make v4test"in the terminal;
     In the terminal prints "test_assoc_abort.c  1 BROK : setsockopt(11):
Invalid argument DUMP_CORE ./sctputil.h: 258"
     Details described below.
     I'm a novice, want your help,pls,thanks very much!
