What is an "ev_base_new(0)"? and which version of libev are you trying
this with?

The process still exists after SIGSEGV? that means you have a signal
handler for it - what does it do?

That's most likely a bug in your program - make sure you never call
functions on the same event loop from different threads, OR use locking.

There are also other rules to follow, such as stopping your event watchers
before freeing them etc., but this probably isn't the problem here.
