Bug #13160

Updated by nobu (Nobuyoshi Nakada) over 3 years ago

When a client connects to a socket, the ruby interpreter crashes with the backtrace at the bottom (used the current version of my gem ICAPrb::Server (this gem has no native extensions)) 

 the ruby vm should not when in receives a connection from a client. 
 This is the last data I get via strace: 

 ``` 
 {sa_family=AF_INET6, sin6_port=htons(39366), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=htonl(0), sin6_scope_id=0}, [2048->28], SOCK_CLOEXEC) = 8
