Reproduce the failure with the 32-bit Linux ./chisel32 client 192.168.x.x:8001 R:1080:socks command, then trace client startup from main.go:450 and client/client.go:298 into the reported runtime.netpoll_epoll.go:45 failure. Compare the runtime error with the platform and build details; done means identifying a reproducible cause and documenting or correcting the failure with a regression check.
