Having skimmed the documentation I can’t see anything which would cause this to fail, but it seems to be throwing an exception/waiting infinitely (this is nested deeply in lwt stuff, so an exception or infinitely waiting may be semantically similar).
let ip_hd = Ipv4_packet.
{ options= Cstruct.create 0
; src
; dst
; ttl= 38
; proto= Marshal.protocol_to_int `UDP
; id= Random.int Int.max_int
; off= 0 }
Any ideas as to why this is silently failing? (this btw should be all mirage
libraries)
