Bug ID: 64573
Summary: Cmd.Start swallows error from fork()/clone()
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go

Proposed fix
Cmd.Start ignores the error code from the underlying fork() or clone() syscall,
instead returning a nil error while setting Process.Pid to 0. If the caller
then tries to Wait on the command, it can end up reaping some other child
process (since waitpid(0) means wait for any child in the process group).
The attached patch should make the behavior identical to that of golang.
