I am trying to extend a old c program with go. Add websocket ability to this c program. first build go as a .so dynamic lib then link the so lib in c program I run the cgo ok in an example program. But when integrate with old c program, c program will send a signal 42 to itself periodly. this cause so lib terminate
rogram received signal SIG42, Real-time event 42.
